Re: Wiring idea

I agree that the ideal is to run lots of cable to all locations but
that is not always practical.  Not because of the cost of the cable
but because of the volume of cables and the size of your node 0.

I use the three coax as follows;
One coax is used by NTL Digital Cable,
One coax is used by Terrestrial Arial (only way to get teletext with
NTL) and Modulated CCTV,
One coax is for distribution, i.e. output from Cable via Video.

If you have a way to do this with two cables I'd be very interested.
