1.2 Antenna Coupler
DANGER
DANGER
ELECTRICAL SHOCK HAZARD
Do not touch antenna coupler cable or
insulator.
Electric shock, fire, serious injury or
death can result if the cables are
touched while transmitting.
Do not touch.
1.2.1 Introduction
The antenna coupler is installed between the antenna and the transceiver unit, and tunes the
antenna to the transmitter.
The importance of grounding cannot be overemphasized. Without a proper grounding, perfect
function cannot be expected.
1.2.2 Ground connection
As the ground connection of a transmitter is part of the total antenna system, it is of the utmost
importance that the ground connection to the antenna coupler is constructed to have the lowest
possible RF-impedance. Losses in the ground connection reduce communication distance.
CAUTION
Ground the equipment.
Ungrounded equipment can
give off or receive electro-
magnetic interference or
cause electrical shock.
