I'm in the process of upgrading my satellite array. Hope to add an AZ/EL rotor system, and build a complete stand-alone satellite antenna system. Right now, I'm sharing my weak signal Yagis for satellite duty.
I'll be limited in boom length to about six feet maximum due to construction of the attic itself. Anything longer, and I start bumping into things. I'd like maximum performance from the space, so I'm wondering if any short length circular polarization antennas are made commercially? Everything I can find (at least in the States) are long-boom affairs.
Feedline will be 3/4" hardline for the 432 antenna, and an SSB Electronics pre-amp. 2 Meters will get 1/2" hardline for feedline, and an SSB Electronics pre-amp. Runs are about 50 feet.
Hi Les, N1LF
WIMO antennas are suitable for your needs.

Hi Les.
It may be worth considering a quad. I used a 4 element one for many years on 2m and was very pleased with the results. I even took one in kit form.....wood boom and dowels + wire, to The Gambia and Cyprus and worked 200 stations from each location on AO-13 and AO-10. - At the end of the visit, I dropped it all in the hotel dustbin.

Hi Les, N1LF
I recommend you the WIMO antennas wich are relatively short boom as you can see downloading the following pdf file.
http://www.wimo.com/download/xquad.pdf
The model 18010 is for 2 meters while the model 18011 is for 70 cm
The phasing harness to get RHCP or LHCP are listed into the pdf file and are sold separately.
