4.3 Corrosion Protection
Perform the following procedures after completing the installation and every
12 months thereafter.
a. Evaluate corrosion protection on all anchor bolts, mount hardware,
reflector hardware, feed hardware, and subreflector hardware. If
protective finish is damaged, clean with a wire brush, remove all rust,
and apply a coat of Rust-Oleum (or equivalent) primer and semi-gloss
white paint. To improve appearance, finish hardware attached to
anodized aluminum parts with Rust-Oleum (or equivalent) semi-
gloss gray paint.
b. Evaluate corrosion protection on surface of mount support tube,
mount legs, actuators, resolver brackets, and limit switch brackets.
During initial antenna installation, the surface and edges of these
parts may receive scratches and will require additional protection. If
protective finish is damaged, clean with wire brush, remove all rust,
lightly sand with 320 grit (or finer) sandpaper and apply a coat of
Rust-Oleum (or equivalent) primer and semi-gloss white paint.
c. Evaluate corrosion protection on reflector surface, subreflector
surface, and spars. If paint is scratched, chipped, beginning to flake,
or just wearing thin, lightly sand with 320 grit (or finer) sandpaper
and apply a coat of Rust-Oleum (or equivalent) primer and semi-gloss
white paint.
4.3.1 Touch-up Painting of Non-Reflective Surfaces
If significant corrosion is found on any part of the antenna mount and
actuators, it should be repaired immediately as follows:
1. Material required:
a. Sandpaper -320 grit
b. Volatile solvent cleaner such as toluene, naphtha or lacquer
thinner
c. Rust-Oleum gloss white paint (unless a special color was used)
