The

makes use of the control circuitry built into the transceiver, which allows the operator to control and monitor
automatic operation of the

, which mounts near the antenna feedpoint. The

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

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
automatically stored in memory for instant recall when the same frequency range is selected later.
Please see the

Operating Manual for detailed information.
