Because of where we travel with our motor home, any conventional antenna like our Winegard is pretty much a decoration since the country switched to digital. It is NOT the fault of the antenna. The current-day digital signal is not forgiving like the old analog signal. You could watch a snowy weak analog signal, but impossible to watch a pixel-crazed digital signal.
If I knew in 2007 what I know now, I would have ordered our rig without the roof-top Winegard antenna. We wouldn't miss it one bit. Where we stay in national parks monuments forests BLMs etc, there is never a sufficient digital signal. The times when we have a signal is overnight in a Walmart parking lot, but the process of repeatedly pointing and scanning is too time consuming for just an overnight stay so we enjoy DVD movies then. When in an RV park in town, we hook up to their cable TV. So for us, we'd be better off without that Winegard contraption and all the caulk & holes in the roof.
I need to mention that we do have a good working signal booster built into the rig, and even this Wingman that mounts to the underside of the antenna. We get a great digital signal, but just don't stay often enough in places where we utilize it. So we wished we never had the antenna.

If we spend a lot more time in our motor home, I would surely consider a satellite dish or other such technical marvel. But we cannot justify the expense....yet that is.
