Thanks for your help!

If the paint had any carbon, metal, or other conductive/reflective
materials in it you'd probably need a new antenna. I know you can
test radome materials in a microwave to see if they are absorbers, but
I dunno about paints.
try asking the GPS antenna mfr.

NEVER paint the radome of ANY electronic equipment with ANY kind of
paint. It wasn't made to be painted.

Go aboard any Navy ship, CG ship, Civilian ship. Climb the mast to
the antenna and look at every piece of fiberglass they're pumping a
million watts through on every radar, TACAN, ILS, UHF, etc., etc., and
you'll see the words "DO NOT PAINT" on all of them.
Wonder for yourself why it says that. S/V "Morning Dew" proves CG
isn't too smart. Think they might have made another stupid mistake?
Larry W4CSC.....DO NOT PAINT radio antenna or radar parts, please?
Not entirely true Larry. In 1970 as a lowly radarman 3rd I took part
in painting the mast and radar antennas on the destroyer I was assigned
to. The paint used was a special brew made just for the antennas.
These were the large rotating antennas and were not made of fiberglass.
I would not paint a gps antenna on a small boat but to say antenna's
are never painted is not exactly true.

That brew is not available at Boat/US. Only the taxpayers could
afford it....(c;
Larry....we can't have that special submarine paint that kills
everything behind the boat, either....

You can get paint that won't effect radar and other RF signals, you
just won't likely find it at your local stores. "Most" paints made
these days, (even latex house paints) have metals in them (notice the
words Titanium white base on most cans?), which are the problem.
