OPERATING CONSIDERATIONS


TM 11-5820-919-12
vswr condition but no permanent change and no retune.
the antenna in use cannot be matched by the antenna
A permanent change in antenna impedance will cause a
turner, or if the turner module is faulty. When operating
retune when the PTT switch is pressed.
in the bypass mode, the presence of sidetone provides
assurance that the rf is being generated and made
available to the antenna. If a short beep is heard at the

BYPASS
MODE.
The antenna tuner is
beginning of each transmission, the antenna vswr is
extremely efficient but some losses are inevitable . The
worse  than  4:1,  but  may  still  provide  useful
bypass mode (ANT SEL switch set 50  position and
communications. If the antenna length, or height above
antenna connected to the BNC connector) can be used
ground, or coax feed line can be adjusted to reduce the
to provide 10 to 20 percent more rf power to the antenna
antenna vswr, the beep will cease, and communications
when the antenna VSWR is less than 1.5:1 (33 thru 75
will be very nearly optimum for that particular set of
ohms). The bypass mode can be very useful if
conditions.
