FC-40
The FC-40 is a microprocessor-controlled antenna
impedance matching network designed to provide
all-amateur-band transmitting capability with the
FT-897/857 Series of transceivers, when used with
an end-fed random wire or long whip antenna.
The FC-40 makes use of the control circuitry built
into the transceiver, which allows the operator to
control and monitor automatic operation of the
FC-40, which mounts near the antenna feedpoint.
The FC-40 uses specially-selected, thermally-
stable components, and is housed in a waterproof
case to withstand severe environmental conditions
with high reliability.
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 5 meters), typically in less than ten seconds.
Transmitter power required for matching may be
as little as 4 - 60 Watts, and matching settings are
automatically stored in memory for instant recall
when the same frequency range is selected later.
