Antenna Mounting

The antenna supplied is of the active type, and is suitable for almost all

applications. It is supplied with a pre-attached, 1-meter RG58 cable,

terminated with a male TNC connector. Before commencing

installation, check that all the items detailed in the contents list have

been supplied. The antenna is supplied with two O-type mounting

clamps for attachment to a mounting pole. Figure 2-2 shows an

example of how this might be achieved.

When mounting the antenna, ensure the antenna has a clear view of

the horizon and is at least 2 meters away from transmission sources

which may interfere with reception. Avoid the direct path of any

microwave links. Using the C-MAP software and the GTU check that the

S/N ratio is at least 33.dB and that at least 4 satellites are in view with

this minimum S/N signal. If you do not get these results check another

antenna position.
