I nstallation Guidelines Regarding Power Line Quality
4 B 4 B
Comtech EF Data has become familiar with the varying quality of the AC
power grid around the world. Observing the following installation guidelines
should help ensure a reliable installation.
Surge suppression: High voltage surges can cause failure of the power supply. These surges
are typically caused by circuit switching on the main AC power grid, erratic generator operation,
as well as lightning strikes. The TRP1000 does not have built in surge suppression; therefore,
regardless of power grid quality at the point of installation, Comtech EF Data recommends
installation of additional power conditioning/surge suppression at the power junction box.
Grounding: The TRP1000 provides a grounding terminal. This is provided to allow grounding of
the TRP1000 to the antenna's grounding network. All installed components should be grounded
to a common grounding point at the antenna.
Electrical welding: If welding needs to take place at the antenna, disconnect all cables from the
TRP1000 except for the ground wire. Cap all RF connections with terminations. This will prevent
damage to the input/output circuitry of the amplifier.
Lightning: Lightning strikes on or around the antenna will generate extremely high voltages on
all cables connected to the TRP1000. Depending on the severity of the strike, the external surge
suppression may protect the TRP1000's power supply. However, if the installation will be in an
area with a high probability of lightning strikes, Comtech EF Data recommends the installation of
surge suppression on the RF and IF cables. One source of these suppressors is PolyPhaser
(
