We decided a few years ago to go down the satellite route as we often found poor reception on some sites. Mind you that was pre digital so things may have improved since the changeover. Providing you have a clear view of the sky its likely you will always get a good picture from a satellite.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
