Ok, this appears to be the OP's report -

Winegard link does not work.
You can get the HBU33 through the Antennacraft site - they have a link to Radio Shack's web site.
The main problem I see with wanting the ABC affiliate WJSU is that it's off-axis from the major group of stations at 12 degrees. You can easily add a second VHF-high antenna to get that station, like an Antennacraft Y5713. However, mixing two antennas with the same bandwidth on a single wire is not recommended. So if you had the HBU33 pointed at 12 degrees and the Y5713 at 45, you could combine them with an A/B switch or with separate tuners connected to your HTPC.
An outdoors installation would certainly be preferred. You'd want the antenna mounted in clear air, unobstructed in the direction of the transmitters by buildings or trees. Whether the dish mount will work for this depends on the location of the mount and its surroundings.
