I *did* read it again. A "conventional com antenna" could mean anything
from a store-bought white fiberglass whip to a store-bought dipole to a
store-bought damn near anything.

And how FAR up the leading edge of the vertical stabilizer? Base right at
the fuselage junction? Six inches up? A foot up?

I understand radio transparent fiberglass. I don't understand the
configuration, and to simply spout "supposes" isn't a real good way to get
decent performance.

I wonder about something else. How long would a "full wave" antenna
have to be for aviation comm radios? I've got some old walkie talkies
that have those very long pull out antenna's, they must be 5 or 6
feet. Are those full wave? And do full wave antenna's get the best
possible reception? Of course, in an airplane, the space limitation is
the problem. I use a di-pole in the vertical stab of my Glasair.
If you use a 1/4 wave antenna, and since it's 1/4 the size of the
radio wave, does that mean you will only get 1/4 of the strength that
is available in a certain location?
