We just use common household bleach mixture to clean antennas that have been up
there for ages, works a treat!

I am seeking advise ...but if I can be pointed to the right
direction, I will be most appreciative.
This summer, I plan to take down my Cellwave Station Master
(repeater antenna) for service, maintenance or painting.
Over the years, moss and algae set in and the bright white
fiberglass finish is beginning to disappear. I seek advise on the following:
1. What cleaning agent would be best to take down foreign
objects in the antenna
2. What paint if any...or preparation therof before application
is neglegible in the optimum performance of this antenna. This antenna has
served us well over the years.
3. Other recommendation.
thanks
chris
Here is a file I picked up several years ago.

Antenna Painting Instructions
The following is courtesy Celwave This is what I received when I
asked
them for a recommendation of what to use in refinishing my 18 year
old
PD455
Celwave receives requests for advice about refinishing weathered
antenna radomes or changing the radome color for aesthetic
reasons. We do not take a position on any manufacturer's paint.
However, Sherwin-Williams seems to make a product, which
should be compatible with radomes and not interfere with the
antenna's electrical performance. The following suggestions are
not a substitute for detailed instructions and mix ratios provided by
the paint manufacturer.
