Yep, had the same problem or like it.
Winegard mid sized White Roof dome.. sorry, I know know the model or what you have.
I thought it was the DISH receiver, 211k and went back and forth with DISH using 4 different Wally receivers, didn't work.
Finally, took it into a Sat Service, Quartzsite, AZ, and it was determined that the Winegard Antenna was the culprit, everything else was tested. Sigh, Had to remove from roof and send the antenna back to Winegard, at my expense, big box, whole unit, for them to inspect under warranty.
after about 10-days got it back and works as it should since then with the DISH 211k not the Wally..
So, bottom line, it could be either the receiver OR the antenna and the only way to check the antenna is to send it back at your expense for Winegard to check it.
Wasn't a Happy Camper on that one.. the only other choice I had was to get the Smaller, Black, Winegard antenna or the Bigger one $1500 gray ones that the "Big Boys" use..
Also, FYI, on mine, I had two antenna outputs. I found, during this 6-month period, that I could switch the cable to the 2nd one and I'd at least get some SD stations, not HD...
That might get you at least connected till you are able to get it all sorted out..
And, No, Winegard didn't bother to explain what it was..
Good luck..
