if you're moving, and presumably doing some redecoration or recarpeting, you can do a proper job if you want, and run the cable under the floors, popping up in the corners of rooms wher you expectto need it, or around the loft and down through the ceilings. You can get an "aerial amplifier" where you plug the aeriel in one side, and it has mutiple sockets on the other, into each of which you co-ax for a single room, like the legs of an octipus.
Don't try to join coa-ax in a junction box or by twisting the wires together, this degrades the signal.
An aerial amplifier needs an electricity supply, the current is very low and it can be taken from a lighting circuit if necessary, but if you are not competent at electrical work ask an electrician to do it.
Unlike electrical power cables, you are allowed to run aerial cables behind skirting board, since no-one will be electrocuted when they drill or nail into it.
If you are having the house rewired, the electrician can include it in his scope of work.
You can have the house wired for internet or burglar alarms at the same time if you want, again, individual cables running back to a central point. Some people put the house server under the stairs.
