Description
This Mercedes tailgate antenna amplifier is a genuine OEM electronic component for the Mercedes W204 C-Class. Primary OEM number 2048702789. It is designed to boost the weak radio signal received by the rear antenna and to pass a stronger signal to the radio or head unit, so that reception stays clear and stable.
Its job is to amplify the signal from the antenna element in the tailgate or rear window and to supply the radio with a clean signal over the antenna cable. Because the antenna signal is very weak before amplification, a reliable amplifier makes a clear difference to the quality of FM reception, especially in areas with a weak signal or while driving between cities. A properly working tailgate antenna amplifier supports good FM and broadcast reception, less noise and signal loss and correct operation of the radio and the audio system of the vehicle.
Common signs of a faulty unit include weak or noisy radio reception, stations that fade in and out, no reception on some bands, a radio that works only close to a transmitter, or an amplifier that no longer receives its supply voltage. When the amplifier fails, the radio may lose most of its stations and the audio quality may be reduced.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 2048702789 before ordering. Professional installation is recommended, and a check of the antenna, the antenna cable, the connectors and the supply voltage where applicable should follow installation.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
