Zaxcom FDP2 filter antenna

FOR TRANSMITTERS

When connected to a transmitter, the filter eliminates transmitter RF noise outside the 35MHz window generated by the transmitter. The filter pushes the noise level down by an additional 50 dB allowing the transmitter antenna to be located very close to receiving antennas without the receiver desensitization that can happen without the filter.

FOR RECEIVERS

In a receiver application, the filter eliminates unwanted RF outside the bandpass of the filter that might interfere with the reception of intended wireless microphones. For example, a walkie-talkie on 460MHz might interfere with a wireless receiver operating at 520 MHz. The use of the filter should knock down the walkie signal so that it does not overload the wireless receiver.
