To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other prob-
lems, ground the transceiver through the GROUND
terminal on the rear panel.
(TVI), broadcast interference (BCI) and other prob-
lems, ground the transceiver through the GROUND
terminal on the rear panel.
For best results, connect a heavy gauge wire or strap
to a long earth-sunk copper rod. Make the distance
between the GROUND terminal and ground as short
as possible.

Each antenna is tuned for a specified frequency
range and SWR may be increased out-of-range.
When the SWR is higher than approx. 2.0 : 1, the
transceiver’s power drops to protect the final transis-
tors. In this case, an optional antenna tuner is useful
to match the transceiver and antenna. Low SWR
allows full power for transmitting even when using
the antenna tuner. The IC-706MKIIG has an SWR
meter to monitor the antenna SWR continuously.
