We just bought the TG. Part of the new install deal for us with Dish Network. They installed the dish on the house, connected up 6 TV's in the house, and the total cost was $300 for the TG. The rest was "free". The Dish HD is AMAZING. Better than the cable we had.
The guys set up the TG in our trailer so we can run three TV's off the TG. But all see the same station. To change the station we go change the receiver box, and they all change to that channel. Not a problem for us.
We take our 211K out of the house and off we go. That receiver also has the Over-the-air module built in. So for local network programming we can use the OTA and bring in the locals...AND it puts those locals automatically into the channel guide too. All I need to do is punch the amplifier button on my Jack antenna. The OTA jack antenna brings in a very clear picture. By doing that we don't need to call Dish and ask for address change. And my daughter who lives at home gets no interruption in her local network service.
They tell me that here in the North East we won't see satellite 129. Too low. I have hooked it up in my heavily treed driveway just to try it out. Initial set up took about 15 minutes. Found Sat 110, 119. I did have to run 100' (two fifty footers connected together) of coax to find an open spot to the west, thru the trees. And the only connector I had was old and corroded. But it did pull in plenty of channels. Picture was a little fuzzy (due to corroded connector???) but very watchable on our 42" TV in a small living space. Didn't try the OTA module. But I assume it works.
Overall, I think the TG will work out OK for us. We bought it for snowbirding in south or southwest. So the western sat's shouldn't be a problem for us. I cannot vouch for the Winegard Anser, or Pathways. But I think the Tailgater is a good deal, and works pretty well with Dish Network. The Direct TV doesn't do HD, so I would recommend Dish over Direct. But that is just me.
