As I currently live in an antenna-restricted subdivision, I have been experimenting with low-profile antennas for a couple of years now. My experience has been that verticals are "iffy" for a couple of reasons: not enough gain at low elevations when the path is longest, a deep null above 40 degrees or so, and fades due to polarization mis-matches. That being said, I seem to do alright on VO-52 right now with a 1/4 wave UHF groundplane on the uplink and a well-hidden 2-meter Eggbeater on the downlink, at elevations between about 20 and 40 degrees.
I am in the process of building a turnstile for 437, which I hope will improve both my uplink on VO-52 as well as my downlink on all the other birds.
