Retrofitting my RVB with HD flat screens so know I can watch shows via antenna. Found a Winegard open box Sensar on Amazon for $50.
I live in a fringe reception area, about 40 miles from all the big antennas in Orlando.
Before the Sensar, I could get about 15-20 channels, depending on the weather and could not get all three majors.
Hooked up the Winegard, peaked the signal (sweet) and ran a new scan;
47 CHANNELS!! Including all the majors.
Well worth it. Very pleased.
My Kharma ran over my Dogma.
