Thanks for all off the replies, I’ll have a look when I’m there later.
The aerial has an F type connector covered by a rubber boot, however the coax cable is run down the side of the caravan through the guttering down pipe so inside the pipe and I would assume has done for 12 years, so it will have been well washed with all the rain and could have perished.
I don’t understand much about coax cable, is the 75 Ohm the resistance reading between the centre core wire and the outer brade?
