I met a gentleman that had a later model Westy, with a Wilson 2000
magnetic base loaded antenna on his roof rack.

I asked him about the ground plane thing, and his response was, that he
had riveted a steel plate under the roof rack, and the riveted a smaller
plate to the top of the rack, to stick the antenna on.

I guess the plate under the rack served as a sort of ground plane, and
he told me there is enough metal under the pop-top to serve as a ground
plane also.

He said it worked well.

I know the Wilson antenna is  excellent, but if in fact it worked good
in this situation, I am sceptical.
