Antenna Coupler

1.2.1 Introduction
The antenna coupler is installed between the antenna and the transceiver, and tunes the
antenna to the transmitter.
The importance of a good ground system cannot be overemphasized. Without a good ground,
this unit will not work properly – if at all.
1.2.2 Ground System
A good antenna can work well only when an efficient RF ground is provided. Without a good
ground system, the full potential of this radio cannot be realized.
DANGER
ELECTRICAL SHOCK HAZARD
Do not touch cable from the antenna coupler.
Electric shock, fire, serious injury or death can
result if the cables are touched
during transmission.
Do not touch this point.
CAUTION
Ground the equipment.
Ungrounded equipment can
give off or receive electro-
magnetic interference or
cause electrical shock.
