would be nice, but running out on the balcony and moving it around all

omnidirectional,
as much of "omni" as I can get, anyway. Since I remember what my
communications instructor told us about loops (they radiate equally
poorly
in all directions g), I figured this would be the most practical
solution
for what I want to do.


Another possible idea could be the turnstile.
That is horizontal, pretty omni, and pretty simple
to build. Just a set of crossed dipoles fed 90 degrees
out of phase. I think you would have less gain vs
the broadside of a dipole, but you wouldn't have the
nulls off the ends.


That's another good idea. Thanks. Are the elements of a turnstile spaced a
quarter wavelength apart, or are they pretty much on top of each other?
