I was getting half dozen channels digitally in the campsite I typically goto in Washington state. I saw this digital antenna add-on for a year, thought it was a gimmick. This was the first trip last week in new unit. Same 6 channels. I broke down bought it for 22 bucks at camping world. It looks like there is no way it will improve anything. It clips into bottom of the Winegard antenna with 4 clips, no tools. Installed, setup the tv for digital channel search. 16 channels. Holy.. I can't believe it works but sure does.
Now you still need to be somewhere that has broadcast range, still parts of washington I camped afterwards no signal. satellite is only guaranteed option. This is a cheap install worth the dollars, everywhere i read people say they have tv improvement too.
