Thanks very much for all that info, that's really interesting and I'm especially happy to have an explanation of why, with very high quality cable designed in the right way, there is no problem with stranding.
Regarding the coaxial cable I found- I checked with the belden catalogue and there is foil shielding as well as braid on that model. I also found a company here called Webro, who are considered as good, apparently. Here's the thing though- the CT-100 cable which are all the ones I found with the similar construction to the UBYTE specced cable, is being phased out- it seems that there are only old stock left of decent manufacturers like Belden and Webro. I spoke to one of the managers at Webro and got told that the CT-100 cable, which used to be the most popular, and which called for exactly the UBYTE-2 design of a pure copper conductor and foil, with air spaced PE dielectric, has now been essentially abandoned in favour of foamed PE, which the satellite industry consider better. So it may be the last chance to make a UBYTE-2 by buying the last reels from good manufacturers. Maplins has never really sold the best, it's just convenient for hobbyists and generally I actually avoid it.
In any case, I've found a local installer with an old reel, and he's letting me strip some back to see if the foil's OK. To be honest, now you've explained stranding better, I'm more tempted to try your original design in the first instance, as it's much easier, and I prefer it in some ways, as I mentioned in the OP!
Anyway, thanks so much again, I really do appreciate your help and support- most kind!
