Mounting pole and mounting base
In order to ensure long life for the antenna electronics and mechanics, the antenna must be
installed properly on a specially designed pole with suitable flange and rubber gasket.
Below are guidelines for installation of the mounting pole and mounting base.
• The pole serves the purpose of protecting the coax cable and its N-type male connector
where it joins the N-type female connector at the bottom of the dome. Further, it is a very
important part of the ventilation system of the dome; the hole in the pipe allows trapped
moisture to escape from the dome.
• The face of the mounting base should be flat as possible (tolerance: within 2 millimeters
of the horizontal plane).
• The mounting base should be parallel with ship’s horizontal plane (tolerance: ± 1°).
•
The fixing bolts of the mounting base should be parallel with the ship’s keel line
(tolerance: ± 2°).
• Weld a ground bolt (stainless steel, M10x40, local supply) to the mast within 50 cm of a
fixing bolt on the antenna unit. The length of the ground wire (local supply) is 50 cm.
