Followed suggestions for OTA TV reception. Got the antenna Winegard HD7696P plus the HDP269 pre-amp. Also a rotor. Rig is set up correctly and well, but during TV use, several stations(10.1 & 20.1) begin to fall out (pixels start to break up and view is visually impaired) and despite my trying to correct with the rotor. Also, before this event of deterioration, everything is working fine. And that is why it is baffling and frustrating(especially when watching a good NFL game). It seems almost like the signal or something is shifting or weakening. It's hard to describe. But it occurs, and any suggestions from you guys is appreciated. Thanks!
