Automatic-Matching 200-Memory Antenna Tuner
FC-40
Installation Instructions
Thank you for your purchase of the model FC-40 Automatic-Matching 200-Memory Antenna Tuner. The FC-40 microprocessor con-
trolled antenna impedance matching network is designed to provide wideband transmitting capability for many Vertex Standard / Yaesu
transceivers
Ú
, 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 1.6 - 54 MHz, typically in less than eight 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. The FC-40 is a current feed design and may not be able to match frequencies that are near 1/2 wavelength (or multiple) of
the antenna element.
Ú
: Check with your Vertex Standard /Yaesu dealer for a list of current transceivers that may be used with the FC-40 Antenna Tuner.
