The radius of the alarm indicated on the package is valid mainly in the field. In the city, where the sent signal is preserved, extraneous radio waves, other interference, the action of the keyfob is reduced several times.

To begin with, you can try to change the length of the antenna. Each antenna operates at a certain frequency, and the manufacturer selects the length according to the signaling transmitter. Car alarm without feedback is one of the first, simplest and most common types of signaling. The main unit is under the dashboard of the car. Small wiring, which comes out of it, and is an antenna. If another wire is increasing on it, you can achieve the expected result.

Feedback signaling is a more modern and efficient option. Antenna in this case is attached to the windshield. It is desirable that at the same time the distance between the antenna and metal parts was at least 5-7 cm. Glass tinting and factory spraying can reduce the effect of antenna. You can try to output the antenna outside the car and install on top of the windshield.

If the financial opportunity allows, it is better to purchase auto alarm with a built-in GSM module. By setting such protection to your car, the owner gets the ability to manage his machine at any distance and receive calls and SMS messages to your mobile phone in the event of a hijacking or hacking. You can receive such information from any, even the most distant point where GSM communications is present.
For those owners of the car that do not have the ability to independently change the range of alarm or install a new, more powerful protection, it makes sense to refer to specialists. They will help choose the most optimal option and install an antenna in the right place.
