• 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 waveguide
up, to prevent damage to
the cylinder that sur-
rounds the waveguide.
Note: For more information, please refer to IMO SN/Circ.271 "Guidelines for the in-
stallation of shipborne radar equipment.
1.1.2 How to assemble the antenna unit

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.
Do not apply the adhesive to
these locations.
3. Pass the Gasket (03-182-3186, supplied) to six sets of the Antenna fixing bolts
