Your line of sight to Pontop Pike is obstructed. In fact your Megalithia picture resembles mine and I have to use TWO TV boosters to overcome this and I still get freezing to NO SIGNAL on the weaker channels in bad weather.
My main transmitter is Winter Hill at 16 miles group C/D aerial but I also have a group A aerial directed on Moel-y-Parc in North Wales at 56 miles and this gives me good reception on four muxes. Comes in handy when Winter Hill is rained off.
