Erika, when you get stuck in special conditions when attempting to locate certain satellites a tripod mounted antenna is a saviour. With equipment like the Winegard Traveler, as you found out, you are limited to locating the western arc satellites. The three western arc satellites are 110, 119, 129. The locals in standard definition for Abilene are on the 129 satellite. As you found out the HD Abilene locals are on the eastern arc 61.5 satellite.
The solution for your situation is 2 satellite dishes. One with your western arc LNBs to receive 110, 119, and 129. There is a fourth coax connector on the western arc LNB. You would use this fourth coax connector to run a cable from your second dish, that you have used to fix on the 61.5 satellite. This would then give you the locals in HD.
I know it sounds like a lot of effort to get local HD stations, but it is the only way in Abilene to get all stations in HD.
Just in case you aren't aware of it, there is a coax connector on the back of you're Hopper receiver, that you can connect a coax from you're roof mounted OTA antenna for local stations.
I also subscribe to Dish and use a Hopper with one Joey. I use a tripod mounted dish. I carry an LNB for both eastern and western arcs, for use depending on where we are located.
After all this, I just had a thought. Why not buy an eastern arc LNB for your tripod setup, this will get the 61.5, 72.7, and 77 satellites. The LNBs are readily available on eBay.
I could have saved a lot of typing and saved you from reading all of this, except the last paragraph.
If you have any questions just PM me.
