6.1 Checking the Installation
This section describes how to check that the antenna system installation is
correct.
1. Verify that the installation is installed in accordance with the Site Installation
Documentation.
2. Check that all cables or connectors are free of damage, and that all cables
(feeders and jumpers) are properly marked.
3. Check that all connectors are properly connected and tightened.
4. Check that the bend radius specification of all feeders and jumpers has
not been exceeded.
5. Verify the antenna directions against the Site Installation Documentation.
Consider magnetic influences from nearby metallic objects and deviations
from magnetic north when using the compass.
6. Check that the correct cable is connected to the correct antenna.
If TMAs are used, check that bias injectors are installed on each feeder.
7. Record remarks, if any, in the test record and forward them to the person
responsible for the site installation.
Note: If a TMA is used, mixing the jumpers or feeder cables damages the
TMA. Verify that the cable markings are correct.
6.2 Calibrating the Antenna Tester
This section describes how to calibrate the Site Master, to achieve accurate
Test results and to compensate for Test Port Extension Cables.
The calibration includes selecting and setting the frequency range before the
calibration, performing the calibration and entering the cable parameters in
the Site Master.
Note: The Site Master must be calibrated each time the frequency range
is changed.
The Site Master also needs to be calibrated if one of the following
messages is shown in the display: ‘‘CAL OFF’’ or ‘‘↑
C’’.
6.2.1 Selecting Frequency Range
This section describes how to select and set the correct frequency range in
