3. Installation
Your antenna pedestal comes completely assembled in its radome. This section contains instructions for unpacking, final
assembly and installation of the equipment. It is highly recommended that installation of the system be performed by trained
technicians.
3.1. Unpacking and Inspection
Exercise caution when unpacking the equipment. Carefully inspect the radome surface for evidence of shipping
damage.
3.2. Site Selection Aboard Ship
The radome assembly should be installed at a location aboard ship where:
•
The antenna has a clear line-of-sight to as much of the sky (horizon to zenith at all bearings) as is practical.
•
The antenna is a minimum of 15 Feet from the ship's Radar, further away if they are high power Radar arrays.
•
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.
•
The antenna is a minimum of 15 Feet from high power short wave transmitting antennas.
•
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.
•
The mounting location is robust enough that it will not flex or sway in ships motion and be sufficiently well
re-enforced to prevent flex and vibration forces from being exerted on the antenna and radome.
•
If the radome is to be mounted on a raised pedestal, it MUST have adequate gussets, or be well guyed, to
prevent flexing or swaying in ships motion. Robust,.
•
This mounting platform must also be robust enough to withstand the forces exerted by full rated wind load
on the radome.
If these conditions cannot be entirely satisfied, the site selection will inevitably be a “best” compromise between the
various considerations.
3.3. Assembly Notes and Warnings
NOTE: Unless otherwise indicated, all nuts and bolts should be assembled
with Loctite 271 or its equivalent.
