I've seen stacked turnstiles...probably in some of the ARRL VHF
literature...might be a good place to start

using stacked 432 and 144 loops? Seems they offer a little gain and a nice
omni directional pattern. If they are high enough off the ground, some of
the lesser lobes would point near straight up. I have used a 0 gain dual
band loop (E-factor) with some success on the closer in passes of VO52, FO29
and AO7, but it has been not very effective with AO51. Of course, I know
nothing would compare with a high gain, parasitic array, but not all of us
have the means nor the location to do that. Stacked loops seem like a good
idea, but I've never seen anyone mention it.
