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.
Just be sure to test in your attic with some simple-but-known-working setup before you spend a lot of effort/money. For reasons that I don't understand at all, I could not pick up ARISSat-1 from the attic, but it came booming in on my HT standing outside. I have just regular asphalt shingles as far as I know, and wooden beams. But SOMETHING was blocking 2M!
