Figure 9: Antenna Mounting Locations
The recommended method for obtaining a satisfactory RF signal is to test a
number of antenna positions and measure the signal-to-noise ratio and received
signal strength (RSSI) for each position. Antenna aiming instructions are provided
in section 5.7: Antenna Alignment on page 40.
Channel Selection -- Identify RF Interference
It is also important to test for RF interference at the intended rooftop or tower
installation site. RF interference can be caused by any wireless system in the area
that is operating in the same frequency band as the wireless. Accurate analysis
requires the use of specialized RF test equipment. The primary purpose of these
tests is to determine what channels are available for use on the wireless system.
Antenna Mounting Equipment
When the antenna location has been established, plans should be made for
installation of the antenna mast or alternative mounting equipment.
IF Cable Routing
Plans should be made for routing the IF cable from the radio/antenna to the
terminal. In some locations it may also be possible to install the IF cable on the
outside of the building. If the building must be penetrated to run the IF cable, it is
important to verify that building blueprints and/or drawings are up to date and
accurate, and that all permissions are obtained for the required modifications.
