7 best car antennas
In the area of reliable reception
The main task of a good car antenna is high-quality signal reception. But which model to choose depends on the needs of the motorist.
For some, listening to the radio is enough, while others want to watch TV programs and use a navigator on the go. For others, high-quality work with the walkie-talkie is important.
Therefore, before purchasing, it is important to decide on the budget, technical features and installation location of the device.
Not so long ago, a 27 MHz antenna was a mandatory attribute of a taxi driver; on long trips, a GSM antenna can be of significant help, allowing you to achieve reliable telephone communication in “dead” sections of the highway (taxi drivers who have now switched to mobile applications should also take a closer look at this class ). For a multimedia complex, you may need not only a radio antenna that improves the sound quality of music, but also a television antenna.
We offer you a rating that includes the best car antennas in various categories. It is difficult to understand such diversity, so we will include in the rating several samples of each class, which can be called the most successful and, no less important, widely represented in the retail chain.
This antenna is not suitable for everyone: both the cable itself and the mounts require holes in the roof of the car. So it is intended primarily for those who constantly need an external GSM antenna, and the anti-vandal design will reconcile the need to drill the roof: there is simply nothing to break. In terms of technical characteristics, the “Triad” is worthy of attention: it is supported as work in standard GSM- ranges 900/1800 MHz, and 3G (2100 MHz) and 4G/LTE (2600 MHz). Support for the 2.4 GHz Wi-Fi band is more of a bonus than a practical necessity. The gain depends on the range: minimal due to the small size for GSM 900 (4.9 dB), highest for LTE (5.8 dB). Main advantages:

9.7 / 10RatingReviewsPut it on the truck. I use a 2DIN radio with a Yandex navigator, maps now load much better. And the same SMS come confidently. |
The domestic inexpensive car antenna copes well with its duties in receiving GSM signals in the 900/1800 MHz bands. In other ranges, its characteristics, for obvious reasons, deteriorate, since its length is consistent with the most popular ones. Therefore, first of all, it is suitable for those who are interested in confidently receiving phone calls. To work in 3G/4G networks, it is better to choose the “Triad”. In the standard bands (to which GSM 1900 is close), the gain of the “Antey 914” is 5.5 dB. Simply put, the signal power increases by 3.55 times - for a relatively compact antenna this is an excellent indicator. It comes with different types of connectors, so you can immediately select the appropriate one (SMA or FME) without the need for additional adapters. The 65 mm magnetic base allows you to quickly attach the antenna to a suitable location. The manufacturer promises wind resistance of up to 150 km/h, but with proper placement in the aerodynamic shade, you can achieve better results. Unfortunately, the points in the rating had to be cut down a little due to their prevalence: being one of the best GSM antennas for a car in terms of price/quality ratio, it is not as widely represented in stores as we would like. But the search will bring excellent results - and at a good price. Main advantages:

9.6 / 10 Rating Reviews I’ve been using it on long trips since I realized that in the most remote places on the highway you can’t even call 112. For the money it’s more than effective. |
The main problem of antennas for CB-band radio stations is their length: alas, a whip antenna must be a multiple in length of an integer number of half-waves of the radio frequency range, and for 27 MHz this figure is 11 m. So in the case of the best car antennas for radio stations, one even has to say not about quarter-wave antennas, but about even less efficient antennas. Specifically, the X-Turbo 80 has a length of 1.8 m, which can be called a reasonable compromise between efficiency and safety of use. With proper tuning, you can bring the SWR to a value of less than 1.2, which can be called an excellent result. What I liked most about this antenna is the workmanship: the rod itself is made of stainless steel, as is the mounting base. In comparison with “folk” antennas with a silumin mounting unit, which can become sour over a season, this is a significant advantage that is worth paying money for. Moreover, the weight of the antenna is small (690 grams), which reduces the load on the mount. Although, of course, most of all, under the influence of the wind, it will still work in bending. The rated power of the antenna is 1 kW with the possibility of short-term operation at 1.7 kW. Although other manufacturers indicate larger numbers, is it worth paying attention to them if even a kilowatt in the CB band can provide an excess communication range? (Not to mention the fact that to work at such powers you need to have the first amateur radio category). Main advantages:

9.7 / 10RatingReviewsWe use it in trophy raids. Compared to cheap Lemm-type antennas, the quality is much higher, the antenna is easily and accurately tuned to low SWR, so the quality of reception and transmission is excellent. |
At one time, this small-sized antenna became a hit among private taxi drivers - with a length of just under one and a half meters, it was securely held by a magnetic base (160 mm - that’s serious!), so you didn’t have to deal with rigid brackets and quickly put it away at night, and the built-in matching coil provided an SWR of 1.2 even after assembly out of the box. Of course, like all magnetically mounted antennas, the exact value of the SWR depends on many factors, including the attentiveness of the owner himself: if you don’t stick the included sheet of adhesive foil onto the base, you can say goodbye to the quality of the connection. So reading the instructions is never superfluous, and this antenna is quite capable of delivering sufficient SWR to operate across the entire width of the CB band. Structurally, we note, it is an almost complete copy of Alan magnetic antennas, the price of which is significantly higher. So, taking into account the more than decent workmanship, this antenna deserves mention in the rating without a doubt. If the thought arises about a permanent installation (which will improve the quality of communication), the manufacturer also has an inexpensive adapter for inserting into the roof in the list of offers. Main advantages:

9.1 / 10 Rating Reviews With a five-watt Alan station - reliable reception in the city, normal modulation quality. I didn’t measure the SWR, and everything is fine. |
A compact active car antenna will be of interest primarily due to the possibility of quick, covert installation - it can be easily placed under the silk-screen printing of the windshield, instead of installing an external antenna, which can be broken and “lost” in a disadvantaged area. Although this installation option will not be effective on every car: like all antennas of this kind, Autofun Pro is sensitive to the distance from the antenna to the metal parts of the body, and to the configuration of the body itself. Therefore, you should not glue it tightly right away, but figure out the optimal location for your car a couple of times. With proper installation, Autofun Pro provides reception of FM radio stations at a distance of up to 70 km from the city, which for the ultra-short wave range can already be called a physical limit: do not forget that In it, radio waves propagate only in line of sight. So, we can recommend it as an option to replace a standard whistling or ineffective outdoor antenna. We especially note that the delivery set contains everything you need, including an alcohol wipe for degreasing the gluing area: Chinese active antennas for 2-3 hundred rubles often lack such little things, but the cost of such a wipe is pennies. Main advantages:

9.5 / 10 Rating Reviews Easy to install and a good antenna. The standard one began to whistle on the highway, but the catch was never better. |
The main advantage of this antenna (like all Supra auto electronics) is its widespread availability in car dealerships: you don’t have to look for it, and it’s inexpensive. Unlike the extremely unsuccessful SAF-7, in which they decided to completely abandon the “whiskers” usual for antennas of this class, here there are two of them, and these are not thin wires on a transparent adhesive base, but elastic pins with adhesive tips - such a solution can be found for example, on radio alarm modules with feedback. As a result, it is easy to install the antenna, and even easier to re-glue it if necessary. The quality of VHF/FM reception of this antenna is pleasantly surprising, considering its price. The manufacturer saves on the ridiculous: the kit does not only include an alcohol wipe for degreasing, but they also clearly regretted the double-sided tape itself. Main advantages:

8.9 / 10RatingReviewsI bought it for myself. For the money it works quite well, although I personally miss the power indicator. I glued it with 3M adhesive tape, it’s not enough of my own, and it’s rather weak. |
With TV signal reception in cars, an expected problem arises: the width of the bands used will require more complexity in the antenna in order to maintain its efficiency in the widest band. But you are unlikely to agree to install an Uda-Yaga antenna on your roof? Therefore, in reality, you always have to sacrifice something. "Triad 690", having extensive capabilities (this includes reception of analogue VHF/UHF broadcasting and digital television broadcasting), is noticeably losing ground outside the city: the level of interference increases, especially on 1-5 VHF channels, where due to the short length of both vibrators it is noticeable the gain drops (in this part of the range it is 17 dB, while at UHF it reaches 24 dB). The built-in amplifier is not bad, it adds practically no inherent noise to the signal. In addition, it has a built-in noise filter controlled by the City/Highway switch. In city mode, only an old ZIL passing by can clog up the image with interference, the ignition system of which is generally a broadband noise generator. To pass the time in traffic jams, watch TV shows at the dacha, if it is not so far from the city - the Triad 690 can easily cope with these tasks. Main advantages:
Minuses:

9.4 / 10 Rating Reviews The standard TV antenna that came with my multimedia center practically did not work. On the advice of friends, I bought Triad, now I can watch football safely in traffic jams. |
Regardless of the purpose, when choosing a car antenna you need to pay attention to at least one parameter - its gain , and for multi-band antennas it will be different for each frequency band.
It is usually difficult to compare different antennas without knowing that gain is measured on a logarithmic scale - an increase of one decibel means an increase in signal power by 1.259 times, so the difference between antennas with Ku 5 dB and 7 dB is already 1.6 times, which very noticeable.
Antennas operating with powerful transmitters will enrich knowledge with another term - SWR , or standing wave ratio. Without going into subtleties and details, it determines the efficiency of the antenna and, ideally, should be equal to unity.
In practice, it will be greater, and you need to remember that for most radio stations, SWR 2 is already the limit above which damage to the transmitter is possible.
Considering that the actual SWR value can significantly drop due to installation errors, you should choose an antenna with a minimum rating value, and a stationary installation on a bracket should be preferred to a magnetic base.

Car radio antenna: secrets of selection
Some car models (especially recently released ones) have a built-in audio playback system.
It includes a player for discs or other storage media, as well as a radio or television, which cannot do without an antenna.
A car radio antenna must have several important characteristics, for example, it allows you to listen to the radio in good sound quality not only in the city, but also at a great distance from the nearest signal sources.
What determines the choice of antenna?
To decide which car radio antenna is best in your case, you should find out what types of these devices there are.
The following antennas are distinguished according to their intended use:
- Standard antenna for listening to audio tracks using a radio.
- An antenna that allows you to catch satellite television signals in a car.
- An antenna with wide capabilities that can be used both for listening to radio and watching television. It is also great for working with a car navigator. The signal level of such a device is much higher than that of previous options.
Price also greatly influences the choice of product. The classic antenna for a radio in a car is considered the most budget-friendly. It can cost from two hundred to two thousand rubles, depending on the manufacturer and the level of signal capture.
A car antenna for watching satellite television costs an order of magnitude more, starting from a thousand rubles. The price range for multifunctional devices is very wide, since they have different capabilities and pick up signals well.
A variety of form factors allows you to choose the antenna that is suitable specifically for your car.
Types of antennas for cars
Based on the installation method, car antennas are divided into two groups:
- magnetic fastening devices;
- antennas attached using suction cups;
- mortise type devices;
- antennas installed using a threaded connection;
- devices mounted with a clamp;
- built-in antennas.
Based on the location where they can be attached, antennas are divided into the following types:
- external fastening devices;
- internal fastening devices.
External antennas, which can be whip or telescopic, belong to the class of passive devices. They are easy to use and quite responsive to signals. However, such antennas are greatly influenced by the external environment. In order for the playback quality to be higher and you can use a lot of radio waves, you will need to purchase an amplifier that will help you hear distant waves.
In addition, you should take into account the fact that not every external antenna will fit the body of your car. It needs to be installed at the highest point of the machine so that it catches the cleanest radio waves possible.
Internal type devices are sold with a built-in signal amplifier. The choice of place in the cabin for their installation depends entirely on the wishes of the driver.
You just need to be attentive to the instructions, which usually indicate the distance of the antenna from the car body.
Indoor antennas are classified as active devices. Although they are good in many ways, they also have disadvantages. For example:
- a high power level sometimes deteriorates the purity of the signal, which causes interference (in this case, the function of switching to a passive state, if provided, will help).
- Active antennas have a higher cost.
Connecting an antenna for a car
Connecting a car antenna is not difficult. Depending on the complexity of the design and the number of functions it performs, the connection method is also determined. So, in some cases, two simple steps are enough:
- Connect the device to the playback center - the radio.
- Provide the device with a power source - a hog network.
This connection method applies to standard antennas.
The most modern devices begin to work after connecting to the radio.
But if such a simple connection is not provided by the manufacturer, it will be possible to start using the antenna only after the following steps:
- Look for a suitable location in the box where the fuses are located and provide power to the antenna using one of these protective devices.
- Or you can use the receiver as a power source. But in this case, the voltage of the device will occur only after the car is ignited.
Installing a car antenna, no matter what type it is, is simple and does not require special abilities or training. Moreover, a device of this type can be made independently.
How to make a car antenna with your own hands
To pick up radio waves in a car, you can use a regular household antenna, which is also used at home.
Any owner can make it, and it doesn’t make much difference whether it has horizontal or vertical polarization.
In any case, its use will cause discomfort when the car is in motion, since it is not designed to catch waves during maneuvering.
But it is quite possible to make an antenna for a car that will work perfectly at speed. At the same time, it will not confuse representatives of various government services checking the condition of the car body.
To do this, you should use a frame-type structure, which should be installed under the pressure of the seal on the rear window. It has a side narrowed towards the top, and is also equipped with a capacitor, which is located in the center of the structure. With its help, resonance adjustment is achieved with the desired radio wave, for example, with a frequency of 27 MHz.
By making the antenna yourself, you will save a lot of money.
The antenna for the radio looks quite simple. If the rear window has the shape of a trapezoid, then a thin MGTF cable with a diameter of 0.5 is installed along its entire perimeter. The length of the structure has the following proportions:
- The length of the upper edge is sixty-five and a half centimeters (plus 65.5);
- The length of the bottom edge is sixty-six and a half centimeters (plus 66.5);
- The length of the side edges is forty-five centimeters (25.5 plus 25.5).
Two wires 45 centimeters long are laid vertically along the glass to the central part of the antenna. They are attached to the capacitor. For ease of use, it is better to twist them in a zigzag shape and install them under an insulating tube.
The wire should only be soldered in the part where it is cut. On the other hand, it must be intact, without any tears or cuts.
The cable should not be too long; it is advisable to use the shortest possible one.
The antenna is connected through a hole, which often serves as communication equipment.
Since the signal level of this device is not as high as we would like, it is better to mount the antenna as close to the glass as possible.

Bottom line
Whatever antenna a person chooses for his car, the most important thing is that it provides him with high-quality reproduction of music and radio programs, making driving on the road more pleasant and exciting.

Active car antennas: features and reviews of popular models
Having a radio in a car is common. Driving without news or favorite music is depressing for a true car enthusiast. But there are drivers who spend 10-12 hours a day behind the wheel.
To solve the problem, you need two things - a radio with a built-in radio receiver and a high-quality receiving device.
We will not dwell on the first aspect, but an active car antenna will help solve the second problem.
Main types of car antennas
Today there are two main types of antennas (based on the principle of operation):
- passive. This is the simplest type of design. The task of such an antenna is to receive the signal and transmit it to the radio. The main disadvantage is the lack of a built-in amplifier. That is, in city conditions, where the signal is strong, a passive antenna can be useful. But it is enough to travel outside the populated area, the receiving device will be powerless - it needs an amplifier. Otherwise, all that will come out of the speakers will be glimpses of speech and noise. To solve the problem, you can go in two ways - install an additional amplifier or buy an active antenna. The second option is much easier to implement, and the costs will be lower; Passive antenna for cars
- active. Such devices are more convenient to operate and configure. A car enthusiast does not need to think about how to strengthen the signal - an active car antenna has everything necessary for clear reception of a radio station or TV even outside the city. Active car antenna
What are the features?
When it comes to choosing between a passive and active antenna, it is enough to remember the operating features and advantages of the latter. We have already figured out that each antenna is capable of catching an incoming signal. Another thing is to convert it and make it powerful enough for ideal sound quality. This task is performed by the amplifier, which is equipped with active antennas.
The quality and strength of the signal largely depends on a number of factors - the distance to the signal source, the terrain, and so on.
For example, if the area around is flat, the signal will arrive without any interference. If there are hills or mountains, the quality may deteriorate.
Having an amplifier built into the antenna can correct the problem. At the same time, the sound is of high quality at different signal strengths.
Video: Review of parcels from China Active internal car antenna amplifier
By the way, passive antennas are not always effective even in city conditions. A large number of concrete buildings with metal reinforcement at the base - all this is an obstacle to the signal and can deteriorate the sound quality, causing unnecessary noise. The active car antenna copes with the task “excellently” here too.
Another nuance is tinting. A simple car film contains a metal coating, which acts as a screen for the signal. If your car has a passive indoor antenna, you may not get good sound.
Of course, if the receiving device is located outside, then such problems due to tinting are excluded. In the case of an active antenna, you can safely tint the car and install the device in the cabin - the signal quality will always be decent.
Features of connecting an active car antenna
Unlike passive antennas, which simply plug into a socket, active devices require a more complex approach. And here the task of the car enthusiast is to solve two problems:
- connect the antenna to the radio;
- power the amplifier from the on-board network.
Here a lot depends on the antenna itself and its connector. For example, in modern devices it is enough to insert the connector of the receiving device into the radio. In this case, a signal is supplied from the antenna to the radio, and in the opposite direction (via another pair of wires) the voltage is 12 Volts.
Unfortunately, you are not always so lucky. More often you have to connect the active antenna yourself. There are two ways here:
- find free space in the fuse box and power the device through your protective device (your fuse);
- power the antenna from the most convenient place (you can take it from the receiver). But in this case, voltage will be supplied to the antenna only when the ignition is turned on.
As for the installation of the device itself, there are no problems here. As a rule, active antennas are installed on a magnet (mounted to the roof) or on the windshield of the car. The second option is preferable for three reasons:
- firstly, there are no wires running along the roof of the car;
- secondly, it is no longer possible to simply steal a device;
- thirdly, fixing the antenna and connecting it takes much less time.
Video: Mounts for car antennas
Most active antennas have a special button that allows you to turn the device off or on.
Why is this necessary? If the car is in the city and the signal quality is high, then additional amplification should be turned off. Otherwise, excessive gain may cause interference.
As soon as the signal weakens (for example, when leaving the country), you can press the button and activate the amplifier.
By the way, an active car antenna also has a number of disadvantages:
- firstly, excessive power can negatively affect the quality of the signal (if there is a button to switch to passive mode, this problem can be easily solved);
- secondly, the cost of an active antenna is much higher than a passive one. But here it’s better to spend money once and no longer worry about poor sound quality.
Review of popular active car antennas
The modern market is quite rich in high-quality and very affordable devices. All that remains is to make the right choice regarding one model or another. At the same time, manufacturers are trying to keep up with the times and constantly improve the functionality of their devices. For example, modern active antennas are capable of receiving not only radio, but also TV signals.
If you choose from simple, high-quality and budget antennas, then a good option is the Triad antenna. Its advantage is full adaptation to operating conditions in Russia and the maximum range of received signals.
At the same time, you can find five different types of such antennas on the market. There is no point in dwelling on all of them - let’s look at the advantages of the most popular model - “610 Standard”.
Many experts put the antenna on a par with such giants as Prologi or Pioneer.
Active antenna Triad “610 Standard”
The main advantages of the Triad antenna include:
- reduction of interference from the ignition system due to the presence of a double filter in the power system;
- the presence of a powerful amplifier capable of optimizing wave signals of various lengths (UHF and MV);
- additional operating modes – “turbo” and “city”. The first option must be activated when driving outside the city, where the signal is quite weak and needs to be strengthened. The second mode (“city”) is suitable for use in populated areas when the signal quality is high enough.
The Triad 610 “Standard” antenna is equipped with a special radio splitter, with which you can enjoy high-quality reception of television and radio signals.
Another popular device is the “Scat” antenna (installed inside the cabin). Unlike the previous device, this antenna is aimed exclusively at receiving radio signals.
The manufacturer of the product is AAC Engineering. The peculiarity of the antenna is the minimum configuration and sale in already assembled form.
This is very convenient, because all that is required of the car enthusiast is to mount the device on the windshield.
The main advantage of the Skat model is metal vibrators on the canvas, which are increasingly used on prestigious antennas. When installing the device, no special skills are required - only caution and accuracy. A napkin is included for cleaning the installation site.
Automotive active antenna "Scat"
Among the main technical parameters it is worth highlighting:
- high-quality antenna assembly made using industrial methods;
- high-frequency Telefunken microcircuit, which is the main active element and ensures high-quality signal reception;
- two operating modes – for weak and strong signals;
- the presence of moisture protection, which guarantees the operation of the device for ten years or more;
- operability at reduced voltage to seven volts;
- A high-quality filter allows you to connect and configure the antenna with any radio.
Conclusion
Buying an active car antenna is the best option for a car enthusiast. These devices are reliable and easy to set up, and most importantly, they provide a high-quality signal.

Which car antenna to choose for FM radio
A car antenna is needed, first of all, so that when receiving radio stations in the FM range, music can be heard from your car radio, and not noise and crackling. But how to choose the best car radio antenna from a large number of options and manufacturers, so as not to buy the first one you come across? Read our review of car antennas and watch the video.
There are so many types of car radio antennas on the market that it’s easy to get confused and make the wrong choice when purchasing: exterior (external) and interior car antennas, passive (without an amplifier) and active. First, we will look at all types of car antennas in order, and at the end of this article you will find a good video review that will help you choose the best car antenna for FM radio.
We also recommend that you read our instructions on how to properly install and connect the car radio.
Automotive outdoor antenna (external)
External car antennas for FM radio are most often installed on the roof, hood or rear bumper. Depending on the mounting method, external antennas are:
- mortise;
- on a magnet;
- with mechanical fastening.
Embedded car antennas
About 20-30 years ago, the most popular type of external car radio antenna was a recessed telescopic antenna mounted on the front fender of the car. Despite the advantages, such as reliable radio signal reception in various conditions, the following disadvantages of external telescopic car antennas can be noted:
- Complex design and low reliability. The hole in the wing into which such an antenna cuts quickly becomes a source of corrosion.
- When moving, do not extend the antenna completely, otherwise it may break due to air pressure. It is better to extend it to the roof level and no more.
- Over time, sections of a telescopic car antenna become loose, rust, the electrical contact between them is broken, and a crackling sound appears in the radio. It is recommended to periodically lubricate it with graphite lubricant.
External telescopic car radio antennas are automatic and semi-automatic (which have recently become widespread). They are very similar in design, as both use an electric motor with a gearbox to extend and fold. These antennas differ only in the way they control the motor:
- Semi-automatic car antennas for radio - the release and folding of the car antenna is carried out by the driver by pressing a special key on the instrument panel;
- Automatic car antennas extend independently when the car radio is turned on and retract when it is turned off. To control such an antenna, you need a special contact in the car radio connector, which is found in almost all modern models.
External car antennas with magnet
Another popular type of external car antennas for FM radio are car antennas with magnetic mount.
External car magnetic antennas have the following advantages:
- very simple design;
- ease of installation;
- low price.
The disadvantages of car magnetic antennas include their relatively short length, which affects the sound quality in difficult radio signal reception conditions, and the need to put the antenna away in the cabin at night.
Automotive whip antennas with mechanical fastening
Another fairly common type of external car radio antennas is whip car antennas for the roof or bumper, made of a solid metal rod.
External car antennas of this type are cheaper and more reliable than telescopic ones, they are more difficult to break, but they are not compact either.
Typically, car whip antennas are mounted on the roof gutter or on the rear bumper. The latter method gives the best results for radio reception in the FM range, since the antenna can be made longer.
This car antenna introduces virtually no additional noise, since the noise is carried back by the incoming air flow.
The disadvantage of this option is the need to lay a long shielded cable through the trunk and rear of the car, and it disrupts the coordination of the antenna with the input of the car radio receiver.
Of course, you need to make sure that the rod does not touch the car body anywhere, and that the shielding braid is securely connected to ground.
Interior car antennas
Interior active car radio antennas stand apart. They are usually mounted on the windshield near the rearview mirror or in the upper right corner.
Interior car antennas, as a rule, are equipped with their own RF amplifier, so their cost is usually slightly higher than external car antennas. In addition, active interior antennas require an electrical connection to power the radio signal amplifier.
Despite the indicated disadvantages, active interior car antennas have undeniable advantages over their competitors:
- Efficiency of radio signal reception in the FM range both in the city and on the highway (automatic signal gain control or city/highway switch).
- In-car antennas do not impair the aerodynamic characteristics of the car.
- They require no maintenance and are inaccessible to bullies.
Active interior antennas under the following brands have proven themselves well on the Russian market:
- Triad;
- Stingray;
- ATM;
- Bosch;
- Blaupunkt;
- Hyundai;
- Supra.
When choosing a car antenna, be sure to take into account the operating conditions of the car. Thus, the interior antennas are not exposed to external influences, but they require a power supply to connect them. And external car antennas are highly sensitive and simple in design, but they have low reliability and are exposed to external factors.
