We live in Javea and have a 1.4m people on the campsite get away with a 1.2m but I know in this area we are lucky with the foot print, go further south and north its not big enough.
I would say Jon @Satandpcguy will spot I have tagged him and he will give you the answer. Bob.
You will not be able to get the Terrestrial channels BBC, ITV etc, I have tried with my 1.1m dish in Benicarlo since the sat change 2 years ago and failed.
We can get them here in Benidorm where we are in a bit of a hotspot.
Are you on a site? Can they provide a hookup?
We live near Murcia and need a 1.9m dish to get all the channels. On the MH the auto system small as it is gets none of the BBC ITV etc outside the house, but around Spain it will at times get a few of them.
