I just put up 60 feet or Rohn 25 with the solid fiberglass rod
insulators and it works out great. I guyed it with Phillystran at 50
feet. I put a spark gap at the base with a gas tube across it to
ground for lightning protection. I'm adding radials now. It was a
pretty easy install. If you live where it freezes though (like I do)
you need to drill weep holes above the solid fiberglass rods to let any
water out of the tower legs.
