Hi Lulubelle, where abouts are you staying? I live in the area.
Generally there is no problems we are not all farmers down this way
in fact we were one of the first area's to receive the digital signal
on switch-over
But that said it is like any area if you are sited under trees, in a valley etc you may encounter some problems, but on the whole you should be OK, I use the fixed status on the van and have stayed in most area's with the Dawlish area being the most problomatic, but still got a picture with the odd "Freeze".
Hope this helps.
