Initial Hook Up
1. Ensure that the antenna has been swept and, ideally, has a return loss of
greater than 20dB (VSWR = 1.2:1). This should be done before connecting
the antenna cable to the system’s output. The power amplifier’s control
system allows the user to change the VSWR trip point up to a maximum level
of 1.8:1, unless a custom VSWR protection system has been requested.
Strive for the lowest possible return loss to maximize transmission distance
and improve operating performance. Unless requested otherwise at the time
of purchase, VSWR levels between the trip point set by the user and 1.8:1 (or
custom VSWR trip point) will cause a fold back in power. VSWR levels past
1.8:1 (or custom VSWR trip point) will cause the system to shut down or fold
back with attenuation to avoid damage.
2. Place the amplifier in its permanent location near a receptacle supplying the
required AC or DC mains voltage.
3. Place an appropriate AC or DC power line protector, conditioner, and/or surge
suppressor across the supply line. This small investment is highly
recommended to protect the equipment from power surges and spikes (not
covered by warranty).
4. Install a lightning surge arrestor or Gas Discharge Tube (GDT) on the coax
near the antenna to protect the amplifier. This small investment is highly
recommended to protect the equipment from lightning (not covered by
warranty).
5. Connect the transmitting antenna cable to the RF OUT female connector on
the PA enclosure’s RF output. On units that have a separate filter or
filter/power supply enclosure after the power amplifier enclosure, ensure to
connect the transmitting antenna cable on the last enclosure in the chain to
the RF Out and connect the RF coaxial between the power amplifier and the
second enclosure in the chain. The system must be loaded into a 50-ohm
load before any power is turned on for over-the-air systems. The Wiring
Hookup is included in the Quickstart package included in shipping and
visually summarizes the aforementioned information.
