I doubt if you'll find anything in the broadcast literature. The
reason is that the standard DA ground system as far as I know, has
always involved strapping radials to a copper strap running along the
line of radial intersection, clipping off the radial wire that runs
past the strap. And the standard ground system wire is AWG solid bare
soft drawn. I think engineering firms like everything done the same
way from one site to the next to reduce variables for a full proof and
get a DA dialed in to the licensed pattern.
Why the teflon insulation?
