I realize that the convention for VHF/UHF sideband is horizontal polarization, but I don't really want to mess around with tower sections and a rotator. I'm looking at antennas that provide an omnidirectional, horizontally-polarized radiation pattern. I realize that such an antenna would not provide the same gain that the antenna pictured above would, but I believe that if you stack them and phase them accordingly, you will add gain. The antennas that I am currently researching are manufactured by KU4AB. Phil offers horizontally-polarized antennas for 10m, 6m, 2m, 1.25m, and 70cm. I'm interested in the ones for 6, 2, and 70cm. The antennas are supposedly tuned for the SSB portions of the bands. They are made using solid aluminum rod, and have stainless steel hardware. The KU4AB.com website claims that pairs of their SQ-432, SQ-144, and SQ-50 can be nested on a mast and only take up 12 feet. Also, according to a claim on the website, Gordon West, WB6NOA, was able to make a 2-meter contact from California to Hawaii using the SQ-144 antenna. That's a distance of 2400 miles. That's exciting. I'm going to continue to look at these (they do get good reviews on Eham.net), but I'll see what else is available, too. I'll have more to report.

The KU4AB antennas were mentioned in the October 2008 QST Radiosport issue in the article by K4GUN and his experiences as a VHF+ rover.
I was also checking them out earlier in the week because I use a G5RV and would like to do some 6m and 2m SSB that the G5RV isn't designed for.
