2. Antenna
Selection
The selection of antenna is also critical to system performance. The selected antenna
must be 50 Ohm impedance and capable of at least 50W. High gain antennas may be
used to increase system coverage. Please take note of licensing restrictions when
selecting high gain antennas. Some services or regions may have antenna gain or system
radiation limitations.
The antenna must be connected to the duplexer with a high grade 50 Ohm transmission
line (e.g. Andrew HELIAX cables). The line must have connectors to match the
connectors on the duplexer and antenna.
Caution: It is important that all antenna cables are grounded at the point they enter
the building. All aspects of the antenna design must comply with the relevant local
regulations.
Post-Installation Checklist
After the repeater has been mechanically installed and all electrical connections have
been made, power may now be applied and the repeater should be checked for proper
operation.
1. Applying
Power
Before applying power to the repeater, make sure all boards are securely seated in the
appropriate connectors on the rear panel and all RF cables are securely connected.
Turn on the DC power source to supply power to the repeater.
2. Verifying Proper Operation
Operation of the repeater can be indicated by the 8 LEDs located on the front panel and
also by LCD prompts.
Caution: Some repeater components can become extremely hot during operation.
Turn off all power and wait until the repeater is sufficiently cool before touching the
repeater.
