I just bought a fiberglass homebuilt project with a conventional com
antenna

What is a "conventional com antenna"?



mounted inside the leading edge of the vertical stab but it
doesn't have a ground plane yet.

If it is installed in the leading edge of the vertical stabilizer, how do
you intend to get a 24" length of conductor forward out into the slipstream?



The instructions call for a 24in by
24in ground plane but there isn't that much room right there at the
base of the tail. Any suggestions as to what would work well?

Until you answer the above two questions, I can't offer suggestions.
