They could be had in stainless steel and they were tough. Like Andrew
cables and connectors, it was wrong to use anyything else.

I can attest, having used countless numbers of the above, that Andrew`s
folded monopole when ordered for the precise frequency and mounted atop
your tower gave a full forward power indication on your wattmeter with
nearly zero indicated reflected power which meant a good 50-ohm match.
All you had to do was install the antenna right and it would give
optimum performance for many years. Your signal reached as far as the
eye could see and then some. Your radio heard signals acutely.

Well grounded to the tower at the top and with proper grounding of the
tower and transmission line at tower top and bottom, lightning is routed
to ground and not to the inside of the attached radio. The antenna just
shook off the lightning strikes with small pits as calling cards. No
harm done.
