A carefully-chosen combination of solid-state switching components and high-speed relays allows the FC-40 to match a wide variety of antennas to within a 2:1 SWR on any amateur band frequency (160 through 6 meters), typically in less than eight seconds. Transmitter power required for matching may be as little as 4 - 60 Watts, and matching settings are automactically stored in memory for instant recall when the same frequency range is selected later.

Please see the FC-40 Operating Manual for detailed information.

Interconnections to FTDX1200 After mounting the FC-40, connect the cables from the FC-40 to the ANT and TUNER jacks on the rear panel of the FTDX1200 Transceiver. Note When the FC-40 is connected to the FTDX1200, TX GND (pin 2) of the TUNER jack and the LINEAR jack (pin 2) are common circuits. Therefore, the maximun voltage at TX GND (pin 2) of the LINEAR jack must not exceed +5V. Cont'd Next Page "FC-40 External Automatic Antenna Tuner"
