Perhaps the terms I used are not technically correct. My experience is
as follows:- I bought a length of 10 metres of what I call ordinary TV
cable, from my local hardware shop and used it run an extension to my
computer so as to run Mythtv on digital channels. When I came to scan
for channels there was insufficient signal strength to get a lock. So,
with digital TV in mind, I replaced the cable with a length of so called
sky cable and the signal strength was much better and Mythtv worked.

The cross section of the two cables is quite different and I suspect
there is a difference in impedance and is really nothing to do with the
difference between digital and analogue signals signals, or is it?
