2-2 LOCATION
This repeater should be installed in a cabinet to protect
it from dust, moisture, etc. When the supplied mounting
handles are attached to each side of the repeater, the
repeater may be easily installed to the 1 g-inch standard
cabinet. Read the following installation instructions
carefully.
1) Select a location to facilitate good ventilation and
emergency maintenance, allow sufficient access be-
tween the repeater and the surrounding walls.
2) AVOID placing the repeater in the environments and
conditions described in the PRECAUTION section on
inside front cover.
2-3 ANTENNA SYSTEM
CAUTION: Transmitting without an antenna may
damage the transmitter of the repeater.
Protect your repeater from lightning by
using a lightning arrestor.
(1) ANTENNA
Antenna performance is important for reliable radio
communications. For this reason, a 50 52 omnidirec-
tional antenna is well worth the extra investment. A
number of high quality fixed location antennas are avail-
able from various manufacturers. Choose one most
suited to your needs.
Use heavy duty stainless steel mounting hardware to
protect the antenna from bad weather and preserve it
for longer periods of time.
(2) COAXIAL CABLE
We recommend using a coaxial cable as follows, par-
ticularly in a fixed location installation of a repeater
where feed lengths are very long.
Use a thick, low loss, all weather-type coaxial cable, and
L-259 CONNECTOR INSTALLATION
1) Slide the coupling ring over the coaxial cable. Strip
the cable jacket to approx. 10 mm (3/8 in). Soft
solder the exposed braid.
2) Strip the cables as shown in the diagram at left. Tin
the center conductor the entire length of the exposed
braid.
Solder Solder
3) Slide the connector body over the cable and solder as
shown at left.
4)
Screw the coupling onto the connector body.
for best results make the connection between the an-
tenna and repeater as short as possible.
2-4 DUPLEXER
This repeater does not include a duplexer. The duplexer
must be purchased separately.
The cables between the repeater and duplexer should
be as short and thick as possible to reduce insertion
loss.
2-5 GROUNDING
To prevent electrical shocks, TVI, BCI, interference to
other stations, and other problems, connect the [GND]
terminal on the repeater rear panel to an earth-sunk rod
or copper plate with the heaviest gauge wire or strap
available and make the connection as short as possible.
*Grounding
WARNING: NEVER connect the ground terminal to
a gas or electrical pipe since the connec-
tion could cause an explosion or electric
shocks.
