Site Survey
The site survey is performed to decide where the best location for the equipment to be installed is. The
radome assembly (ADE) should be installed at a location aboard ship where:
1.
The antenna has a clear line-of-sight to as much of the sky (horizon to zenith at all bearings) as is
practical.
2.
The antenna is a minimum of 15 feet from the ship’s radar, especially high power radar arrays.
3.
The antenna is not mounted on the same plane as the ship’s radar, so that it is not directly in the
radar beam path.
4.
The antenna is a minimum of 15 Feet from high power short wave transmitting antennas are not in
close proximity.
5.
The antenna must be installed in a rigid mounting location that will not flex, or sway, in ship’s
motion or vibration.
6.
The Above Decks Equipment (ADE) and the Below Decks Equipment (BDE) should be positioned as
close to one another as possible. This is necessary to reduce the losses associated with long cable
runs.
