Jim, Davis RF BuryFlex is the way to go. It has a PE jacket, a stranded copper center conductor, it's direct burial (just as the name implies), and it handles direct sunlight exposure very well.
I have been using it for 15 years, and it all came from the same roll I bought from The Wireman at the Shelby NC Hamfest. It's a little more expensive today, but I plan to buy another roll soon. 73, Tony K4QE On Sun, Aug 25, 2013 at 11:25 AM, Jim Garland <[email protected]> wrote: > My forthcoming 160m vertical requires about a 700 ft run of coax.
