Yes he had a machine in the loft that showed readings and when he switched a button the screen had the actual TV pictures on. He said 100% same as you'd get outside with next aerial down for same price.
I have DMX10 in loft outside would have been DM15.
So on Wednesday I take it I should be saying all advice (Freeview & CAI) websites say it should be roof mounted?
If as expected they say not cahnging I have to go to CAI? As no other options left?
Thanks for help everyone
