Thanks for the replies everyone!

With a gain of 10dB per way, if you use only one of them and split it later, you'll soak up most of that 10dB gain in splitting.

It comes with a single powered amplifier (one lead in and one out) which the instructions only show being connected from the aerial to a single TV via the supplied white cable. I'm a bit confused as the aerial itself has 4 f connectors for leads to different devices so presumably this amplifier isn't intended to serve up to 4 possible devices, it's been provided to serve just a single set with the option of buying others if more than one set is being connected to the aerial.
I don't know much about these things but I think you're saying at the end of your post is that, regardless of whether I use amplifiers, running separate RG6 cables from the new aerial to each TV should provide a much better signal to each than splitting a single cable to feed them.

Try something like this http://www.blake-uk.com/dml-log-periodic |
That's very similar to what I've not got.
Interestingly while fiddling around with the rg6 cable last night (10m long) I found that it was providing a TV picture on certain channels even before being connected to the aerial. This is what made me think that the cable isn't well shielded and is acting like an aerial on its own.

A couple of quid from Amazon etc.
The ideal method is to use a distribution amplifier if there's more than 2 sets. |
Yes I have a couple of those Y shaped splitters lying around somewhere. I'm not sure if the problem is a connection one though because it still happens when I'm just walking around the cable and not actually touching it. It's just like when you're watching TV using a cheap indoor aerial and lose the TV signal temporarily when people start moving about in the room.
