Our outdoor TV aerial, which looks like this:

blew down in the wind l is now lying on our roof supported by the coaxial cable which luckily is clamped to the mounting bracket. It's pointing roughly 70-90 degrees to where it was and has the brick chimney stack and roof structure lying between it and the transmitter (Crystal Palace) yet it's still providing a good signal on all but a few channels - mainly HD. Currently this aerial is connected into a simple junction box which feeds 3 TVs around the house via 3 cables. As we seem to be in a strong signal area and I'd rather not have an outdoor aerial, I've bought one which I want to install in the loft.

I've run some coaxial cable into the loft and have connected one end to the new aerial via one of the 4 F connections and the other end to a single TV temporarily to see how it performs but am finding that the cable seems to be acting as an aerial itself. As I move it around (with the actual aerial stationary) or even walk past it coiled on the floor, the TV picture comes and goes. So I'm wondering if the cable isn't very well shielded and I need something better to prevent this interference or whether something else is wrong. Ideally I'd like to run a single cable from the loft aerial to the existing junction box to feed the 3 TVs rather than running 3 separate cables all the way from the aerial to each TV but have no idea if this is feasible. Guess it depends on how good the signal is.

Can anyone advise please?
