I'm assuming you're talking about the new Rayzar thats similar in appearance to a dome satellite antenna.
I installed the Rayzar when they first came out to replace my Sensar IV and it failed the 3rd time I tried to scan for stations. I have to say Winegard was good about the issue and paid for a full replacement, including the labor. The new one is actually finding two more stations than my old Sensar IV did from my home location. So far I'm happy with it as it seems stronger, and the auto search feature means I don't have to search for signals. For me it's been a win-win, and I don't miss the old Sensar IV one little bit (especially having to find digital signals).
That said, something you didn't mention, but might be an issue. Is the amplifier working on the new Razar? If I shut my Rayzar off, the amplifier goes with it leaving me without any signals. Just a thought.
