6.1 INSTALLATION
This section provides tips for selecting an appropriate site, choosing an
antenna system, and reducing the chance of harmful interference.
6.1.1 General Requirements
There are three main requirements for installing a transceiver—ade-
quate and stable primary power, a good antenna system, and the correct
interface between the transceiver and the data device. Figure 6-1 shows
a typical Remote installation.

6.1.2 Site Selection
Suitable installation sites should provide:
• Protection from direct weather exposure
• A source of adequate and stable primary power
• Suitable entrances for antenna, interface or other required
cabling
• Antenna location that provides as unobstructed a transmission
path as possible in the direction of the associated station
(s)
These requirements can be quickly determined in most cases. A possible
exception is the last item—verifying that an unobstructed transmission
path exists. Radio signals travel primarily by line of sight, and obstruc-
tions between the sending and receiving stations affect system perfor-
mance. If you are not familiar with the effects of terrain and other
obstructions on radio transmission, the discussion below provides
helpful background.
