I recently stayed on the riverside site (Rountree Park) which is notorius for poor TV reception. I have a 2008 swift and was parked next to my brother in law who has a 2013 Lunar. he had no problem with tuning in his TV whilst we could only get the BBC channels
and after a few miutes the signal started to break up becoming totally un-watchable. It would appear that the main difference is that he has A vision plus VP4 booster and I have the basic Vision Plus booster. My question is "Would replacing my current booster
with a VP4 or VP5 make much difference?" or "Rather than spend £30 to £35 on a replacement booster would I be better putting the difference to and getting a basic satelite system?"
