Default antenna

A "whip" or monopole antenna such as this requires a ground plane to operate
properly. In general, a metal airplane with metal fuselage in all
directions will serve very well

In a plastic airplane, a "ground plane" of several (four is the accepted
number)radials quarter wave long (about 24") coming out at right angles at
right angles from the antenna is a requirement. A single 8x10 aluminum
bracket isn't going to cut it.

Would perforated aluminum foil or aluminum screen embedded in the
skin and bonded to ground do the job? I'm assuming it wouldn't make for
a strong lamination, but as a ground plane it seems kind of tidy.
