The Clansman BCC-543 VHF Automatic Antenna Tuning Unit or the TUAAM is used with Clansman VRC-353 and other Clansman VHF radio sets such as the PRC-351 and PRC-352 Man-Pack radios in vehicle roles using an Initiate Box.
The ATU is normally fitted inside the Land Rovers wing antenna box and automatically matches the selected frequency to the antenna to give optimum performance and achieve maximum range with the radio set. All Tuning and matching functions are carried out automatically by sensing the antenna impedance at the required operating frequency. NSN: 5821-99-630-6156. Supplied in good condition.
