At least part of the problem, I think, is that I don't have anything
even close to line-of-sight to any TV transmitter at all. I'm probably
30 miles from the Mendip transmitter with the Quantocks in the way. I'm
also about 20 miles from the Stockland Hill transmitter, but that hardly
carries anything more than I can already get from the Mendip one, it's a
lot lower power and the Blackdowns are in the way, too.)
