> Through good luck I've acquired two 5-meter diameter Scientific Atlanta
>dishes. I hope to use one myself for amateur Earth-Moon-Earth
>communications. I thought the other would be a good SETI antenna. I'd love
>to set-up a SETI station myself, but I can't afford the high end computer
>hardware.
> The antenna is a Scientific Atlanta Model 8126 with a Model 8023 mount.
>The antenna was used as a television downlink feed. One unit has a horn
>feed with a sub-reflector (cassegrain feed?) that uses WR229 waveguide that
>has a 3.3-4.9 GHz frequency range. The F/D measured 0.372 (.375?). The
>antenna is entirely dismantelled and stored at my house. The reflector is
>comprised of 24 solid aluminum sheet petals. The entire antenna, central
>hub and angle braces are alumunum. I'd guess the total weight to be about
>800 pounds. The antenna and mount can be transported in the back of a large
>pickup truck. The antenna mount is designed to be fixed on a particular
>azimuth/elevation, with about 70 degrees of elevation range and maybe 15
>degrees of azimuth range. I have detailed photos prior to disassembly.
> I would like to trade for amateur radio VHF-microwave gear, a good PC
>system, or best offer.
> A last note... I also have a 12 ft dia and 8 ft dia aluminum dish
>skeletons that I found in the aluminum dumpster at a local scrap yard. Both
>have an F/D of .375.
