Art is correct. Vertical antennas require radials to avoid ground loss.
Norizontal dipole radiation in free-space is perpendicular to the
antenna.

Art also asks: Is anybody using two whips as a dipole?

I`m sure they are. Saw a hamfest vendor selling loaded whips and mounts
designed to mount two of them as a dipole. There have been discussions
in previous threads about this application. Hope there are new responses
to Art`s question.
