When mounted in a plastic airplane vs. on a metal airframe, the
monopole whip antenna + ground plane can be as annoyed by things
nearby. The essential difference can be that the longer length of the
dipole makes installation free and clear more of a problem, though.
I bugged a retired, aircraft antenna engineer about what radiates on
the back side of the monopole's ground plane if of the recommended
dimension and a plastic plane. He thought huge backlobes might be
hurled into outer space. I stumbled upon a thread of ham types and
engineers whose 200+ messages had multiple theories and didn't settle
anything. So...which is more efficient???
