ACV Car audio replacement rod aerial

This car antenna is a windscreen antenna for the reception of DAB and DAB+ radio transmitters in vehicles. It works as an externally operated active antenna, which receives radio signals from the vehicle window and forwards them to a car radio via a separate cable. The external 12 V power supply provides power to the active switch of the antenna and thus improves the sensitivity when the signal is weak. The installation is usually done by placing the antenna on an inner glass panel, laying the 3 m cable in the area of the dashboard and connecting the power cable to a 12 V power source in the vehicle, as well as the coaxial cable to the car radio. This solution is particularly suitable for situations where roof or column antennas are impractical but reliable digital reception is required.
