We know there is a coaxial for the freesat & one that comes from the tv aerial into a very obvious aerial box, but then we've no idea what the third grey one is.
It ends (or starts) in a box that appears to have aerial type ports on the side.
It goes through the fence gap between fence & wall & ends up going into the ground next door.
Any ideas? Neighbour has volunteered to cut it, but I've very strongly said no that for safety reasons.
