now SGC has taken the next step and added an intelligent tuner to
the control station.
The MAC-200 is something completely new, an antenna switching
system that also provides built in intelligent tuning capability to
trim the line before going into your transceiver. The MAC-200 has
170 built in memories to remember both the tuning parameters and
the antenna at a variety of frequencies. It has all of the
sophistication developed over the years with SGC’s Smartuner line
of antenna couplers. However, the MAC-200 is an antenna
TUNER intended for installation near the transceiver rather than at
the antenna feed point..
The MAC-200, located as it is in the radio room at the point where
all antenna feed lines come together, provides tuning at the end of
the antenna feed line rather than at the optimum point, the antenna
feed point. SGC Smartuners provide for matching of an antenna to
the feed line, thereby minimizing SWR and losses on the line. The
MAC-200 allows control of multiple antennas from a single box
and tuning the antenna system in order to connect to the
transceiver, but it must match the impedance as reflected by the
transmission line to the device.
