The FC-40 is a microprocessor-controlled antenna impedance matching network (auto tuner) for the popular Yaesu FT-897 and FT-857 transceivers. It is designed to cover all amatuer HF bands when used with an end-fed random wire or long mobile whip antenna. A 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 5 meters). Up to 100 matching settings are stored in memory for instant recall. Rugged, waterproof housing is designed to be mounted at the antenna feed point.
