Chuck, They are hot dip galvanized and there is no sign of rust (yet). When I took this apart I checked every bit of hardware for looseness and rust, found nothing suspect.
One thing I did notice when I got the antenna was the factory Y splices and heat shrink over the 1/4 wave 35 ohm matching section were anything but water tight. I added waterproofing (butyl rubber and tape) in which I had total confidence but now paranoia is making me doubt myself. :-) I will rip into it today.
