I was wrong in referring to the power supply as the amp I should have known better.
Back to the problem. I do have the Winegard Batwing.
I checked for the 12 vdc art the ant head,13+ volts.
I have bypassed the "box full of buttons" selector box and connected the ant co-ax from the PS directly to the TV input. TV input set to "ant", and still see "NO SIGNAL" the screen.
I have not done any recent changes or projects having to do with the TV co-ax hookups.
When previously (yesterday) hooked up to the parks cable system, all was OK. As was the Sat dish connections. We have sense changed locations by several hundred miles.
Thanks for any more advice you might have
