See my previous post on page 4 of General Discussions "Free over the air dgital TV". As stated, the picture is crystal clear.
These receivers are for the older TVs that do not have a built-in digital tuner. You need an antenna like the batwing on your RV or just the swept design that most of us had on our homes prior to cable. The "digital antennas" being pushed now are just marketing ploys to get you to buy the antenna. On some of the older TVs you cannot view the on air channel guide, but must simply enter the number of the station you want to watch ... I haven't found any way around this. Go to
www.titantv.com and enter your zip code to see the channels available in your area.
