8.11 Radio Antenna
There is one radio per track. For a radio to work properly, it needs an antenna.
When installing the radio antenna, follow the directions that came with your antenna and:
1
Mount the antenna onto the outside of the bungalow, preferably on the roof of the
bungalow.
If you mount it on the side of the bungalow, make sure the entire antenna is above the
roofline.
2
Route the coaxial cable from the antenna-mounting base to the SmartScanIS
enclosure.
In sheet metal, use a rubber grommet in every hole through which you route the cable.
3
Install an N-type plug onto the end of the cable.
4
Connect this plug to the coaxial arrestor on the Surge Protection Subassembly (in the
SmartScanIS enclosure).

If this is a single-track site, go to

If this is a double-track site:

Repeat steps
1
through
4
for the radio in the other SmartScanIS enclosure.
b
Go to
