VI. INSTALLATION
The PA8-1AC amplifiers are designed for mounting in a standard 19-inch rack.
When picking a location in the rack, considerations must be given to RF cable
lengths as well as cooling. Mount the amplifier away from the sources of heat
where dust and other debris are not likely to clog the cooling fan and as close to
the antenna as practical. Keep coaxial cable runs short, avoiding sharp bends
and pinching. Avoid loose connectors at the ends of the coaxial cables. The
antenna should be matched to a VSWR better than 1.5:1 for best results. Higher
VSWR will degrade the performance of the amplifier.
1. Connect the DC power using #14 AWG wiring if possible and certainly no
lighter than #16 AWG. To avoid a possible fire or other possible damage,
make sure a fuse or circuit breaker is installed at the power supply end of the
wires. Use the same size fuse as the amplifier’s fuse.
2. Connect the antenna to the “RF OUT” terminal with a 50Ω coaxial cable and
type “N” male plug.
3. Turn off your radio transmitter. Connect it to the “RF INPUT” terminal with a
50Ω coaxial cable and type “N” male plug.
4. For safety, ensure that the rack and all equipment connected to the amplifier,
have proper ground connection. Do not rely on coaxial cable shielding.
Assure the installation has proper lightning protection.
