Dear John,
Thank-you so much for your detailed reply.
The current areial is indeed a screw fit rather than twist which is
good news because it reduces the number of connectors!
Does the "military" grade version of the cable,

work any better? I can't see if the only difference is that the outer
sheath is tougher or if this actually means that the cable is less
lossy. I reckon that its going to be a maximum of 20ft from handset to
the aerial.
I'll drop the RAYNET guys an email. Once again, many thanks for your
help. I'll certainly post here if I end up doing this with any advice
for anyone else that might find this post!
Many thanks,
Alex
