3.2.2.2 Service Antenna Installation
It is necessary to find a good location for the service antenna in order to achieve
best coverage.
For indoor coverage, the following conditions need to be considered:
1. Avoid installing near metal or obstacles that may influence its coverage
performance.
2. Install the antenna at least 2m above the floor for the best coverage and for
the convenience of passers-by.
3. The service antenna should not be installed close to the donor antenna to
avoid isolation issues.
For outdoor coverage, the following conditions need to be considered:
1. Avoid installing near trees or other obstacles that may influence its
coverage performance.
2.
The service antenna should not be installed too close to the donor
antenna to avoid issues with isolation. The angle between donor antenna
direction and service direction needs to be larger than 90 degrees. The best
condition is when the donor and the service antennas are installed in
opposite directions.
