Unpacking
After unpacking, immediately report any damage to
the delivering carrier or dealer. Keep the shipping car-
tons.
For a description and a diagram of accessory equip-
ment included with the repeater, see ‘SUPPLIED AC-

n
Selecting a location
Select a location for the repeater that allows adequate
air circulation, free from extreme heat, cold, or vibra-
tions, and away from TV sets, TV antenna elements,
radios and other electromagnetic sources.
n
Antenna connection
For radio communications, the antenna is a critical
component, along with output power and sensitivity.
Select antenna(s), such as a well-matched 50 ˘ an-
tenna, and feedline. 1.5:1 or better of Voltage Stand-
ing Wave Ratio (VSWR) is recommended for desired
band. Of course, the transmission line should be a
coaxial cable.
CAUTION: Protect repeater from lightning by using
a lightning arrestor.
NOTE: There are many publications that describe
proper antennas and their installation. Check with
your local dealer for more information and recom-
mendations.
