Sennheiser A 9000 B1-B8 Antenna Booster

The remote-controlled antenna booster contains eight highly selective filters that each allow a 24 MHz frequency window to pass. This adds significant safety to the system, as unwanted signals are blocked directly before the first active component. The frequency window can be remotely selected from the receiver. The linear RF amplifier with very high resistance to intermodulation can compensate for cable losses of up to 14 dB. The booster and receiver together check the cable loss on the RF cable and adjust the gain automatically. The A 9000 omnidirectional antenna incorporates the AB 9000 booster, which is directly mounted on the surface of the antenna.
