• For X-band radar, if it is
necessary to lay down the
radiator before you fasten
it to the Antenna Unit, lay
it down with the wave-
guide up, to prevent dam-
age to the cylinder that
surrounds the waveguide.
• If the de-icer is installed, a two-pole breaker (supplied locally) must also be installed.
Note: For more information, please refer to IMO SN/Circ.271 "Guidelines for the in-
stallation of shipborne radar equipment.

How to assemble the Antenna Unit
The Antenna Unit consists of the antenna radiator and the Antenna Unit chassis, and
they are packed separately. Fasten the antenna radiator to the Antenna Unit chassis
as follows:
1. Coat the hatched area shown in the figure in step 2 with the supplied adhesive.
2. Remove the protective waveguide cap from the waveguide on the radiator brack-
et.
3. Pass the Gasket (03-182-3186, supplied) to six sets of the Antenna fixing bolts
(03-182-4188, supplied, w/two flat washers), and then coat the threads of the An-
tenna fixing bolts with the supplied adhesive. Set the radiator on the radiator
bracket.
