Your AN/GRC-106 radio set's 50-
ohm antenna needs a little exercise to
do its best.
Sure, your whip antenna gets the
most use. But ±ive your AN/GRA²50
antenna group a workout, too. That
Keeps the radio set in fighting trim.
Without the workout³ antenna
coupler contacts corrode. This leads to
poor contact and bad readings on the
antenna tune and load meters.
These bad readings can show you a
tuned and loaded antenna when you
don't have one. The antenna won't
accept your aMp's output, sending
some back to the set´ This reflected
power can damage the radio.
!±²³I´µ¶·¸
µeep contacts clean by tuning your
transmitter into theAN/GRA-50ora
dummy load.
