5 - Feed system installation*(Refer to feed system installation instructions)

* For monopolarized feed systems with freq. below 10 GHz, and for dualpolarized feed systems below 11 GHz, the feed system must be installed before radome installation(due to mixed mounting design). If your feed system is not concerned, skip this step, you can install it later.

Replace the 2 M5 bolts on the reflector rim, 90 counter-clockwise fromthe shroud junction, by the M8 bolts as described below.

- Install the radome over the shroud aperture- Push on the J-Bolts springs to hook them in the

radomes eyelets.

- After J-Bolts complete installation, adjust the radometension with the 1st M5 nut to have a spring length of20 mm on each J-Bolts (proceed by opposite J-Bolts).

- Then lock each 1st nut in position with the 2nd one withusual wrenches.
