Digital TV Reception is not great in our area and sometimes we lose reception when conditions aren't favourable. Being UK Freeview, I'm pretty sure it uses the DVB-T2 standard.
Anyway, when reception is poor, varying the position in which the (RF Coaxial) cable running from the wall to the receiver is draped improves or worsens reception. Also, when you set it in a working position, as you move away it may mysteriously then stop working. Surely this defies science, but everybody else must have experienced the same thing?
Anyway, the socket has been replaced, the connections are certainly excellent, we've tried different cables, there are no stray strands within the wall box etc. so the only explanation I can come up with is that the earth or metal components of the wall box pick up signal from surrounding objects, or shielding of the cable is inadequate. Is there an established wisdom why the setup is sensitive to cable position?
I should mention - not everybody has a cathedral directly between their aerial and the transmitter. Perhaps this mysterious behaviour is down to some unknown property of his holy lordship.
Just to be clear, I'm not asking how to fix the problem, e.g. by amplifying the signal at source, although sensible fixes would also be welcome.
