We had the Satfi dome and it was excellent all over the UK and in France. In Spain it worked as far down as Valencia in Spain. The only drawback we found that on occasions if there were trees in the way, you did not know which way the dish was pointing. It was more prone to loosing the signal.
We now have a 85cm Sat dish mounted on the caravan and it will work right down into southern Spain for Sky channels, but not BBC or ITV. We use a Sky+HD box as too many hassles with Sky Q plus costs. The dish was installed by SG Home Leisure and even with trees in the way, it still picks up a signal.
I will second Dave and Cyn question which should be the first thing considered. Then also if trees in line a problem,why we always used a tripod we could move about.
