Proceed as follows:
1. Using a Spectrum analyzer, measure the received signal from BTS at the Donor antenna port near
the Repeater.
2. Adjust the Donor antenna direction to receive the maximum signal strength.
3. Compare the received signal strength with the calculated signal strength from the design phase.
In case of discrepancy, check for one of the following:
• Antenna out of direction
• Antenna tuned to side lobe instead of main lobe
• Antenna connector or antenna cable faulty
• Line-of-sight problem (obstruction), etc.
4. Register the signal strength of the downlink channel for the system operation phase.
3.1.6 Antenna Connections
CAUTION! DO NOT CONNECT THE ANTENNA CABLES TO THE REPEATER
BEFORE VERIFYING THE INSTALLATION PARAMETERS.
CAUTION! DO NOT POWER-UP THE REPEATER WITHOUT EITHER THE
ANTENNAS BEING CONNECTED OR THE ANTENNA CONNECTIONS TERMINATED
WITH DUMMY LOADS.
To connect the antennas to the Repeater
NOTE: If the coaxial cables are NOT weather-resistant type, wrap the exterior coaxial cables with
insulation and holding tape (Type 3M Rubber splicing tape) for environmental protection and to
ensure longer lifetime.
1. Install the antenna cables along their path to the Repeater, and connect them to the Antennas.
NOTE: Be sure to use low loss cables.
2. Connect the Donor antenna to the Repeater BASE port. (Donor antenna specifications and
installation criteria are described in section
2.1).
3. Connect the Service antenna to the Repeater MOBILE port. (Mobile antenna specifications and
installation criteria are described in section
2.2).
4. Verify all RF connectors are tightened and the cables and antennas are secured.
