Brand New Vizio 40 inch TV problem, HELP

Unfortunately, even if you get an HD receiver which is capable of High Def, if you are using a dome, the dome can only receive SD programming and the picture will be small and it will be cr@ppy. However, it will be a more simple setup as you just select the appropriate HDMI input. That will also allow you to connect your existing OTA TV antenna to that one coax connection, do a new channel scan and you will be able to watch all of your favorite local TV channels in FULL HD! The OTA TV is the VERY BEST TV viewing available as it is not compressed like the other options. Want to watch the Super Bowl and you have Cable or DTV or DISH? Switch to the OTA antenna for a substantially better picture!
If I read you last post correctly there appeared to be a complement in there. If so, many thanks!

Compliment,...yes. I just didn't want to get too mushy. :)

All of this has been in a brick house. The only exterior antenna is the Direct TV unit on the roof which has double LNB and azimuth, elevation, skew adjustments.
The large TV room is where the 46" Sony TV lives, with large Spectrum HD receiver (HDMI connections) AND with large Direct TV HD receiver (HDMI connections). Both feeds deliver excellent picture quality. What I should've said in my long post is simply that I might spend the money to duplicate this arrangement for the new Viscio in the master bedroom. Obviously, I'm not a TV guy.

The 2003 40 ft Dutch Star(special-ordered, picked it up at the factory), parked in the backyard, is the one with the Trac-Star dome (nothing like in-motion feature). Except that it got hurt by large hail about 5 years ago, and the parts for the Trac-Star were no longer available. I've been using a small portable dish that I set up on the ground.
Gotta go get some shut-eye. Thanks again
