That's brilliant. Thanks for that information Briantist. I thought a group A aerial would be the one to go for. Is there anyway of telling on an existing aerial what gain it is and whether a particular group or wideband?
Touch wood, the signal has been consistent now for the last week so lets hope it continues!

Chris: There will be a "red band" on a group A aerial, but the only way to find out the actual gain is to check in the technical specifications.
I'll keep my fingers crossed for you too.

That's good to know. Thanks. I'll keep a lookout for one. Cross fingers, we have had an uninterupted signal now for quite a while although as I write this, it is now SNOWING again so it will be interesting to see if the signal gets interupted again. There is a signal at the moment.
Many thanks
