Down in Cornwall at the moment with the inlaws and the babies and.....
It's peeing it down here and I just spent 30 minutes realigning their Sky dish with nothing more than a ladder, pliers and a Sky box signal meter, which is useless.
Trees are the issue here, which have grown, so just raised the dish on the pole and mildly realigned it. The Sky box signal strength and quality now read about about 2/3s of the arbitrary scale but some channels are still breaking up. The dish needs a proper relocation really.
