How to connect the Bosch antenna to the car radio
How to connect the antenna to the car radio: instructions for selecting, connecting, making your own hands
The antenna for your car radio differs in some ways from receiving devices for other types of equipment. Structurally, it represents a quarter-wave vibrator, which is equipped with various kinds of additional amplifying elements.
In essence, these elements and the vibrator itself are the line to receive the signal. However, the car body itself is used as the grounding, which allows the line to operate in an uninterrupted manner.
Choosing an antenna for your car stereo is based on the specific requirements you have. For what purpose the antenna will be used? When it will be operated? How often you will be using it?
Varieties of antennas for car radios
According to their purpose car antennas are divided into four types:
- receiving TV signals. these antennas have an extended range of action, the driver and his passengers will be able to watch TV channels on the road;
- Receiving data from satellites. used to set up and use navigation systems
- Car communication antennas are for talks on the road between the drivers of different vehicles;
- Universal, combining the characteristics of all of the above types of antennas.
Depending on what purpose the device will be used, you need to select and the antenna itself.
The satellite dish for the car. rather, the luxury than the necessity
Keep in mind
The type of antenna depends on the nature of your travels. If the car is used within the limits of urban and suburban areas, it is better to choose a passive rod antenna of medium length, perfectly working in conditions of strong reception. For long journeys, work in settlements remote from big cities, choose an active antenna. It has a built-in signal booster. Usually such antennas are made inside the cabin to prevent moisture penetration inside the antenna amplifier. However, when entering a city, crossing power lines such antenna may be “clogged” by external interference.
At the moment you can distinguish only two types of antennas for cars, which differ in their location:
- outside the car. external. Installation of such kind of the aerial should consider features of a car case design, after all from a choice of a place of fastening in many respects will depend and quality of received signals. In most cases, pin antennas and telescopic TV antennas act as external antennas. However, their connection may require additional equipment in the form of amplifiers;
- on the inside of the car. inside. Traditional for many drivers GPS antenna, which is fixed on windshield. It already has an amplifier and is suitable for almost all models of car stereos.
Today the most budget-friendly antennas for receiving radio signals can be considered. The device of such aerial represents a simple amplifier which adequately functions in any place as in a city, and beyond its limits. When buying an antenna that receives radio signals, special attention should be paid to its range. The greater the operating range, the wider the territorial coverage of the signal area.
Antennas, which receive TV signals, will cost several times more. Higher cost is due to their complex structure and the ability to achieve a clear picture on a portable TV in the cabin of the car.
expensive aerials receive signals from satellites. Their main task is to correct the route of the car, so even the slightest inaccuracy must be excluded. It is clear, that satellite aerials for the car cost more at the expense of complexity of a design and more qualitative work.
If the car is equipped at once several devices (a radio recorder, TV, the transmitter of signals from the satellite, etc. п.), it is not reasonable to buy a separate antenna for each of them. It’s enough to install a universal one, which will catch all signals with the same quality and will provide uninterrupted work of the existing devices.
The universal receiving device for the car costs cheap and provides trouble-free operation of several devices
Connecting the active Bosch antenna
Hello again))) To all who have responded, thanks for the hints about bulbs In gratitude for this I will tell in pictures how to connect the active aerial, by the example of the Bosch aerial. First of all, as it is described in the instruction choose where to install the antenna, in a corner, as I have or across the width of the windshield. There is a triangle on the package which is supposed to help us to position the antenna on the glass, we cut it out. We fix in its grooves a mounting disk, we remove a protective film from a disk, and we glue a disk on glass, in a place of installation of the aerial.
After mounting the whiskers, these ribbons are removed. Put the antenna whisker on the disk pin, having previously removed a small section of the protective film. Push and gradually pull the protective film from under the antenna’s tendril, glue it to the windshield. Do not throw away the protective film. Then glue the following braid along the limiting strips, taking care not to stick the antenna on them.
Then, with a confident jerk)))) remove trim of a rack, and lay a cable in free grooves, on clamps of a hose of washing liquid.
Unscrew screws fixing the glove box and take it out. Installing the cable. The most interesting thing is the cable to power the antenna amplifier. It is necessary to connect it on a jack of a radio recorder.On a special 12 volt cable. This cable is available in all (non-standard) boomboxes and is called the antenna control cable. As a rule it has a standard blue color.
It is left to put a glove compartment in its place We take a deflector from an air duct, take a special tool and by feeling put a rod of the air duct in its place.
It is better to install the braid with the central air ducts, which can be easily taken out with the radio removed from the inside. PPS and yes I bought myself a mifun (for those interested in other people’s radio with a removable panel) The sound is very high, even a tear, but about that later.
and I’m trying to quit smoking. Clutch, gear, Monte Carlo though not outside the window, but in the soul for sure))) Happiness and good luck to all ;)))
The Bosch Autofun PRO antenna
When I replaced the LG with the Alpine, I also installed the Bosch Autofun PRO active car aerial, because someone outdoors pulled the native one and it seemed to be more necessary. The already known to audiophiles internal antenna Bosch Autofun got a new look. The case of the device became more streamlined that has made its design closer to the style of the modern cars interiors. No need to call a specialist to install the antenna. it is simply glued from the inside to the windshield of the car without drilling or any other preparatory operations. The current absorbed by the built-in signal amplifier is small (30 mA), which allows you to save battery power even if you listen to the radio for a long time while the car is parked.

The instruction to the antenna says differently
The manual for this active antenna from Bosch says differently. According to the manual, the antenna arms and the antenna body itself should be mounted at least 6 centimeters away from the edge of the car body. But I did it almost up close and I haven’t noticed any degradation, everything works fine. Best of luck to you too!
Installation or replacement of the player requires connection of different cables, which ensure operation of the car multimedia system. When installing audio equipment by yourself the user should know how to connect the antenna to the car radio. Erroneous actions lead to incorrect operation of the radio, as well as failure of electronic components or fuses.
Before you connect the antenna to the car radio, you should find out the type, as well as design features of the used equipment. Products for receiving radio signals or other waves can have a built-in amplifier that connects to the vehicle’s onboard network. A special filter is installed in the construction of the standard equipment, which provides removal of background noise and increases the quality of signals received. The device is placed under the interior trim, has an additional power supply from the vehicle’s battery.
The choice of antenna is made by the manufacturer for cars with factory built-in equipment or prepared to install a loudspeaker system. The owner of the vehicle can remove the existing product or not use it to receive radio signals. optional equipment is installed when using a head unit with a television receiver or navigation module. Additional modification or replacement of the existing antenna is required for the placement of special CB radios, which are used by heavy vehicle drivers.
The instructions for the antenna say otherwise
The manual for this active Bosch antenna says differently. According to the manual, antenna arms and body itself must be installed from the edge of the car not less than 6 centimeters. But I did it almost exactly and I didn’t notice any deterioration, everything works fine. I wish you good luck too!
This high sensitivity car interior antenna is mounted on the inside of the car window and provides excellent signal reception in the AM/FM range. In this article we will understand the components of the antenna and its installation.
The package includes main module of the antenna, which we are going to describe later, plastic cover consisting of three parts, set of limiting and fixing stickers, set of screws and clips, radio receiving element, wet wipe and special gel for grounding.
Design and Installation
The design of the antenna allows to establish it in the top part of an internal side of a windshield or in its corner. The choice depends on the user’s preferences and the possibility of installation, which can, for example, be obstructed by the rearview mirror.
Before installing the components, it is worth using a damp cloth.
Then cut out of the box that came with the device “reference corner”. it is highlighted by a dotted line.
Guided by the “cardboard corner” should be glued to the glass plastic overlay with the manufacturer’s logo. It is this insert that will be visible from the street. On the selected place, next to the windshield gasket, it is necessary to glue limiting strips and by orienting on them to fix the radio element consisting of two parts.
It also received an adhesive layer, so there will be no problems with its installation. It is necessary to cut the ends of radio element on plastic insert which we have already glued on a windshield, it is necessary to take into account that the distance from a body of auto must be not less than 50 mm and to fix them by the special stickers. The next step is to install the main module. to do this, you need to fix it on the already glued plastic insert and cover them with the main cover, which should later be tightened with a screw from the delivery kit.
Bosch antenna tendrils (Bosch)
In my Lada Kalina 2 in a car showroom installed the internal antenna together with the music. Yes did not spare my money, the most expensive put “Bosch“. I did not specify in time, what should be put. The antenna worked fine, but I did not like that the antenna tips were glued to the glass in a visible place. They were visible, and I thought it was ugly. I have heard or read somewhere on the internet that the Bosch antenna antenna tendrils do nothing. That the active antenna will work just as well and catch radio stations without them.
Hello again))) Thanks to all who responded, for hints about bulbs In gratitude for this I will tell in pictures how to connect the active antenna, on an example of the antenna firm Bosch. First of all, as it is described in the instruction choose where to install the aerial, in a corner as at me or on all width of a windshield.
There is a triangle on the package which is designed to help us in locating the antenna on the windshield, cut it out. Fix installation disk in its grooves, remove protective film from disk and glue the disk to the windshield at the antenna location.
After mounting the whiskers, these strips should be removed. We slip on a pin of a disk of a whisker of the aerial, preliminary having unglued a small section of a protective film. Push and gradually pull the protective film from under the antenna’s tendril, glue it to the windshield. Do not throw out the protective film. Then glue the next whisker along the limiting strips, taking care not to stick the antenna on them.
Then, with confident jerk))) remove trim of a rack, and we put a cable in the free grooves, on clamps of a hose of washing liquid.
We unscrew the self-tapping screws fixing the glove compartment and take it out. Putting the cable. The most interesting thing is the cable for power supply of the antenna amplifier. It should be connected to the car radio socket.On a special 12 volt cable. This cable is available in all (non-standard) car stereos and is called antenna control cable. As a rule it has a standard blue color.
Where to put the device
In the matter of installation and connection of the car antenna, the choice of place for its installation is of great importance. The traditional place for an active device is the upper right corner on the windshield or behind the rearview mirror. The passive can be on the body of the car, usually mounted on the roof.
Active aerials are usually mounted on car roof in such a way the received signal quality improves
It is recommended to prepare all necessary tools and materials so that the connection does not take too much time;
- soft lint-free cloths to clean the surface;
- Glue or double-sided adhesive tape;
- A drill with a drill bit diameter identical to the diameter of the wire from the antenna;
- Bolt, nut and lock nut for grounding.
Any antenna, regardless of type or design, must be mounted on a clean surface. Before installation it is necessary not only to remove dust or dirt from a glass or a body, but also to degrease a surface (for this purpose ideally will suit white spirit). At purchase of devices of factory production in the complete set it is offered and the special cleaner.
The kit includes not only the equipment, but also a special cleaner for the car surface
Step by step instructions for installation on the roof
If the cable length from the package is not enough, you will need additional. The cable must be shielded and have a resistance of 75 ohms.
- At the place of installation it is necessary to drill two holes: with a diameter under the antenna mount and 5 mm. auxiliary.
- Metal on the place of installation is scraped from the inside of the salon.
- To avoid corrosion the place of installation is treated with mastic on the inside and sealant on the outside.
- For installation it is necessary to make an insulator (spacer) from copper and fluoroplastic washers which the cable is soldered to.
- The connection between the insulator and cable must be sealed.
- Install the antenna on the roof and tighten the nut insulator on the inside of the cabin.
- Running the cable from the antenna to the car radio under the car trim.
- Connect the antenna to the car radio and check the signal quality.Watch video on installing antenna
Connecting to the boombox
Installed equipment for receiving radio waves should be properly connected to the head unit. On a correctness of installation depends on a radio sensitivity and quality of reproduction. When driving the car antenna plug vibrates in the socket.
A loose installation leads to interruptions in signal reception, which leads to failures in radio reception or the appearance of noise or interference.
To install the external antenna use the fixing through the hole or on the magnet. The cable from the magnetically assisted equipment is routed into the passenger compartment through the door seals. This causes fraying of the cord insulation resulting in interference. A deformed seal also allows water to enter the vehicle’s interior.
For installing the antenna on the roof requires drilling a mounting hole and a channel for entering the cabin wiring harness. Connecting cable must be shielded with estimated resistance of 75 ohms. To place the equipment on the roof will need to remove some of the overlays located on the racks, and then slightly move the all-molded ceiling liner. Element is removed carefully, because deformation will be visible on the flat surface of the panel.
After drilling the holes, you must apply protective mastic to reduce the risk of corrosion. The body of the antenna is mounted on the roof through the rubber seal additionally smeared with a sealant for outdoor works.
This method reduces the amount of water entering the car interior.
The signal cable is attached to the active element through a set of plates made of copper and fluoroplastic.
Some vehicles have holes for fixing the common passive antenna on the roof or fender which are covered with plastic or rubber plugs.
On cars that provide for the installation of acoustic equipment, there are regular harnesses.
On some cars, you’ll have to pull an additional cable connecting the output of the antenna to the car stereo. The cord is pulled under the interior trim elements and under the carpet laid on the floor. After that, it is required to install the antenna, which is fixed with the original nut.
If the owner of the car does not want to cut the body or he does not have the proper skills, it is allowed to install the antenna for car radio in the cabin of the vehicle. The device is placed on the instrument panel or the rear shelf. Then you need to lay a connecting cable and connect the antenna connector to the head unit plug. The disadvantage of using a passive indoor receiver is interference and a small radius of radio reception.
To improve the reception quality a separate signal booster is used which is plugged into the connection cable. The wiring diagram of the device includes positive and negative wires. The minus signal comes from the car body or the metal power frame of the dashboard. Connect the plus cable to the nearest switch. But with the ignition off the antenna does not work, so it is recommended to commutate the wire directly to the plug of the radio.
Before you connect the active antenna you should choose the place for mounting of the case on the preliminary degreased surface of the windshield. The whiskers are stretched along the top and side edges to ensure that the driver’s view is preserved. Fixing of elements is made with standard glue layer (protected with transparent tape) or with pieces of double-sided adhesive tape. It is also possible to place the antenna pin on the metal roof panel. In this case, the quality of reception is impaired, because the body is an additional shield for radio waves.
To supply voltage to the amplifier the power plug on the radio is used, which has a separate cord with blue insulation. The corresponding wire is pulled inside the dashboard, the connection is made by soldering, followed by protection of the joint with insulating tape.
When switching is important not to mix up the minus and plus, because a mistake will lead to failure of the amplifier.
Negative wire, covered with black insulation, is mounted on the car body.
If the head unit is not equipped with a separate power output, it is allowed to switch the device to the sockets of bulbs of illumination of buttons or switches located on the instrument panel. It is recommended that the circuit be protected by either an in-line fuse or an additional fuse.
Features of connection of the active automobile aerial
Active antennas work like this. Whiskers catch the radio signal. The amplifier clears it of interference and transmits it to the receiver. But the device needs power for this process. This is where the problem lies.
The driver buys an expensive model with an amplifier. Connects it to the car stereo. And nothing changes. the signal is still distorted. When buying a device, it is important to clarify how the amplifier will be powered: from an external source, or from the car radio.
Connecting to the car radio
Installed equipment for receiving radio waves needs to be properly connected to the head unit. On correctness of installation depends on sensitivity of radio receiver and quality of playback. When driving, the car antenna plug vibrates in the landing slot.
If the installation is loose there are interruptions in signal reception, which leads to failures in the reception of the radio station or the appearance of noise or interference.
To install the outside antenna use a fixing through a hole or on a magnet. The cable from the magnet-supported equipment runs through the door seals into the passenger compartment. This causes the cord insulation to become frayed, resulting in interference. Also, a distorted seal is leaking water into the interior of the vehicle.
To install the antenna on the roof, you need to drill a mounting hole and a channel for entering the interior of the wiring harness. Connecting cable must be shielded with a calculated resistance of 75 ohms. To place the equipment on the roof will need to remove some of the overlays located on the racks, and then slightly move the all-molded ceiling liner. Remove the item carefully, because the deformation will be visible on the flat surface of the panel.
After the holes are drilled, you must apply protective mastic to reduce the risk of corrosion. The body of the antenna is mounted on the roof through the rubber seal additionally lubricated with a sealant for outdoor work.
This method reduces the amount of water getting into the car interior.
The signal cable is attached to the active element through a set of plates made of copper and fluoroplastic.
Some cars are provided with holes for attaching the common passive antenna on the roof or on a fender which is covered with a plastic or rubber plug.
The vehicles which are equipped with acoustic equipment have regular harnesses.
On some cars, you’ll have to pull an additional cable connecting the antenna output to the car stereo. The cord is pulled under the interior trim and carpeting laid on the floor. After that you need to install the antenna which is fixed with the original nut.
If the owner of the car does not want to cut the body or he does not have the proper skills, it is allowed to install the antenna for car radios in the cabin of the vehicle. The device is placed on the dashboard or the rear shelf. Then you need to lay a connecting cable and connect the antenna connector to the head unit plug. The disadvantage of using a passive indoor receiver is interference and a short range for receiving radio stations.
To improve the quality of reception, a separate signal amplifier is used, which is cut into the connecting cable. The wiring diagram of the device includes positive and negative wires. The minus signal comes from the car body or the metal power frame of the dashboard. The plus cable is connected to the nearest switch. But with the ignition switched off the antenna does not work, so it is recommended to switch the cable directly to the plug of the radio.
Before you attach the active antenna, you need to choose a mounting location for the body on a previously degreased windshield surface. The whiskers extend along the top and side edges, ensuring that the driver’s view is preserved. Fixing of elements is made by standard glue layer (protected by a transparent film) or pieces of double-sided adhesive tape. It is also possible to place the antenna pin on the metal panel of the roof. In this case, the quality of reception is impaired, since the body is an additional shield for radio waves.

The negative wire, covered with black insulation, is installed on the body of the car.
If the head unit is not equipped with a separate power output, it is allowed to switch the device to the sockets of light bulbs of buttons or switches, located on the dashboard. It is recommended to protect the circuit with a regular or additional fuse.
Peculiarities of connection of active car antenna
Active antennas work like this. The whiskers are picking up the radio signal. The amplifier cleans it from interference and transmits it to the receiver. But for this process, the device needs energy. And therein lies the problem.
The driver buys an expensive model with an amplifier. Connects it to the radio. And nothing changes. the signal is still distorted. When buying a device, it is important to clarify how the amplifier will be powered. from an external source, or from the car radio.
