Antenna Mounting

Obviously the mounting of the antennas needs to be taken with extreme
care. The following is a brief checklist to ensure for antenna mounting concerns
to be checked prior to acceptance of a cell site:
1. What are the number and type of antennas to be installed?
2. What is the maximum cable run allowed?
3. Identify and rank obstructions that would alter the desired coverage.
4. Rx-antenna spacing is adequate; diversity requirements are met.
5. Isolation requirements meet with other services.
6. Antenna-AGL requirements are met.
7. Antenna-mounting parameters are met.
8. Intermodulation analysis is completed.
9. Path clearance analysis is verified (if applicable).

This previous list is just preliminary and can easily be altered based on
the situation at hand. However, the list should be modified to meet your
particular system-design requirements.
When installing on a tower, the physical spacing or offset from the tower
must be selected to the tower’s structure which either enhances or does not
alter the antenna pattern desired. In addition to the pattern issue, care
must be taken in ensuring that there are not degradations caused to the
system because of unwanted energy from adjacent systems. It is suggested
that an interference analysis be conducted for every site to ensure the
proper isolation requirements are met.
When installing on an existing building, the following few items should
be considered in the design phase. 592
