[TowerTalk] Lexan

[GALE STEWARD]

Hi John'
I used LEXAN tubing and rod to make a replacement
driven element insulating arrangement on my 40-2CD.  I
never trusted it to be UV resistant although it may
well be.  I covered it with a layer of #33 electrical
tape.  I had the antenna down last fall for some minor
repairs and there was no UV damage evident.  I also
have some fiberglass pieces on the linear-loading
sections of my 80/160 vertical.  Instead of covering
with tape, I painted the pieces and they are in
perfect condition after 8-9 years out in the elements
(SE Pa.).  Both schemes seem to work.

73, Stew  K3ND...
