If you're willing to sacrifice performance, you can try using no insulators
at all, but YMMV... Many hams who've made a major capital and labor
investment in a tower and antennas prefer to take the least risky, highest
electrical performance approach and go with Phillystran or fiberglas.

I'm with Frank on this. By the time you start buying 502s (around $6 each),
guy grips (around $6 each) there isn't a whole lot of difference in cost,
especially if you have a short tower. I have used Philly from the 80s and
also
did the Polyrod fiberglass thing. I am not a big fan of the Polyrod since
it started getting "fuzzy" real quick in the Florida sun. It is a lot cheaper
though. The catch on Polyrod is you have to put in a BIG order (usually a
group thing)
The Philly I am putting up on my tower out here in KH6 is from the 80s and
early 90s, and other than some surface rust on the potting connectors, is
still in excellent shape. I highly recommend the Phillystran route.
