A potentially ambiwlans type of question here - When I drive over the river (Trent is it?) on the M180 here I find that, even though I'm more elevated than the surrounding area, I lose phone signal - why is that?
Same problem over the top of the A628 at Woodhead, coming back from Manchester, I have signal between the hills, as soon as I pop out onto the top, the signal drops like a stone??
