Reviews: Winegard Rayzar antenna

We have a 2004 Sunseeker so whatever is on top we use now. Not sure what brand or what. I'll check tomorrow. So you're saying the antenna up top is better than the Rayzar? So who is the Rayzar for? Or the Flat Wave? Guess I need info on the entire picture. We don't stay in one place, use the rv to get from here to there and stop as we travel. Some places we get a few channels, some none, some quite a few. I turn the antenna from inside the unit and get what we can. We can do cable if it's available, not always the case. Thanks for responding though. It's help me decide.
