Metallic paint and composite antenna signal strength

Absolutely NOT. That is the LAST place you want a ferrite-foil dipole. You
want a "stock" "B-B on a BNC" with a pie plate ground plane. Dipoles waste
half your expensive transmitter power warming up the ionosphere.

sounds like a good place to use Wier's foil antenna setup :-)

Sorry for the delay in my response. I was dragged away on vacation.

The antenna is designed to be "GLUED" in place. See the info at:

The paint in question is made by Dupont and has actual medium and small
Aluminum flakes in it.

I am going without the metallic paint just to be sure, but glad I was able
to get some thoughts on the topic.

Thanks all.

No, that wasn't the point. You CAN'T bond (as in glued to) a ground
plane type of transponder antenna to the plastic fuselage. If you were
so ... ummm ... thoughtless as to try and bond a dipole type antenna for
transponder use half your transponder power gets radiated into outer
space. Where, as I understand it, no ATC facilities yet exist.

Actually, ATC probably does have facilities somewhere in "outer" space.
Local space has yet to comply with the EPA regs.

Sorry, if I had known you were spending hundreds of dollars of your money on
fives and tens of dollars worth of antennas I'd have told you to go to the
manufacturer who is taking your money and ask the question. After all, you
should be getting SOMETHING for your money.

I will stand by my assertion that if you do not use a ground plane for your
transponder antenna you will be wasting half of your transponder power.
