9.12 Radio Antenna
At double-track sites, there is usually one radio per track. This is the case when internal
radios are used, but not always the case when external radios are used. When external radios
are used, the components supporting track2 don't need to have their own radio. Instead, they
can use the radio that supports track1 (see Section 2.3.4)
For the radio to function properly, it needs an antenna. However, STC doesn't supply the
antenna or the hardware to install it.
When installing your antenna, follow the directions that came with your antenna and:
1 Mount the antenna onto the outside of the wayside enclosure, preferably on the roof of
the enclosure.
If you mount it on the side of the enclosure, make sure the whole antenna is above the
roofline.
2 Route the coaxial cable from the antenna mounting base to the SmartScanNG²
detector.
In sheet metal, use a rubber grommet in every hole through which you route the cable.
3 If needed, install a PL-259 UHF or a type-N plug onto the end of the cable.
4 Connect this plug to the type-N jack on the top of the SmartScanNG² detector.
The detector chassis is equipped with a type-N jack. For those using a PL-259 UHF
plug, a UHF-to-type-N adapter is included with the shipment.
5 If this is a double-track site, repeat steps 1 through 4 for the radio in the other
SmartScanNG² detector.
