I have a Roadtrek (small Chevy van converted to a mini-motorhome) which has

Wanting to set up good ground to air communications ability on 123.5 and
123.3 with a Tait mobile radio in the vehicle. * The problem is establishing
a ground plane with the fiberglass roof.

Other than a magnetic mount antenna on the metal hood....any suggestions?

Wouldn't mind a fiberglass whip type set-up if the performance gains
justified it, but I would like it to be functional while driving....also
don't know how to establish the ground plane.

Appreciate any advice. *Thanks!

I'll just point out that 5/8 wavelength whip antennas do not need a
ground plane. 1/4 wave ones definitely do. You may well do better with
a 5/8 one for lots of reasons. Your need there will be a secure mount
location to the longer whip.
