I mean no offense, but anecdotal evidence about painting pagers doesn't take
the place of a controlled environment test when it comes to making general
pronouncements about antennas inside of one paint or the other.


Of course not, but the fact the paint DID affect the operation of the
pager shows that there WILL be an effect on the operation of the
antenna inside the painted radome. The controlled environmental
testing will determine the magnitude. Kinda like giving a dose of a
substance to a mouse. It squeaks, drops dead quivering ten seconds
later... it would be safe to say the substance wouldn't be good to
ingest, but you'd have to do more testing to find out just how
dangerous it is.

So far as I know, the paint could have leaked inside, the pager could have
crapped out from natural causes...


Nope - with a new pager case, the thing worked like new. And FWIW,
the testing of the pager did involve a radiation test fixture inside a
Lindgren screen room, and lotsa nice HP test equipment.

I have absolutely no idea. I can tell you how to run a test on it if you
would like.


Had a customer paint his pager case with metalflake paint - didn't
work worth squat when he was done. I suspect the effect would be the
same on any radome (since that's what a pager case is).
