The AF13 filter decreases mutual interference between two VHF transceivers operating with antennas close to each other, for instance, in one vehicle. The filter is used between the RF13 transceiver and the ZV13.1, ZM13.1 amplifier with a mobile or stationary­ antenna. The filter allows simplex and half duplex communication between transceivers. If the filter is turned off then signal can pass through bidirectionally without filtering.
