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.

J-Bolts tension
- Install the radome over the shroud aperture
- Push on the J-Bolt’s springs to hook them in the
radome’s eyelets.
- After J-Bolts complete installation, adjust the radome
tension with the 1st M5 nut to have a spring length of
20 mm on each J-Bolts (proceed by opposite J-Bolts).
- Then lock each 1st nut in position with the 2nd one with
usual wrenches.

7 - Pre-assembly of the mount (Feed system not shown)
For an easy operation of the bolted joints, and correct torque tightening, « Anti Seize » installation paste must be applied to all threads of bolts and fine adjustment spindles.
After this, keep the lubricated threads free of dust and dirt! (a Torque Table is attached for specifications)

16 - Final Check
When the installation of the antenna has been completed, it is necessary to make sure that the installation instructions have been followed in all
aspects. It is especially important to check that all bolted joints are torque tightly locked (mandatory).
