If you can't contribute anything positive to this question, then stay
out of it, with your trash!

I have a 10m base loaded mag mount antenna, that I had to put a piece of
felt over the magnet as not to scratch a new vehicle.

When I did this I apparently changed the capacitance between the mag
mount and the roof of the vehicle. Someone suggested that I might want
to replace the felt with either a large balloon or a large prophylactic
as it is thinner and the capacitance would then return to almost where
it should be.

Positive comments only!



Maybe black, electrical tape on the bottom of the mag mount (applied to
that mag mount, of course.) Would be thinner, but I suspect it might
still cause some problems with increased capacitance. Dave

Dave (and John Doe), the idea is to incease capacitance. Large capacitance
is a solution to the problem not a cause of problems, agree?


I don't know, but if that's the case, than a thinner medium between the mag
mount and the roof would have a higher capacitance than a thicker one, like
felt. Or it least I think it would... If so, than Saran Wrap might be the
answer.
