[TowerTalk] tower base rod weatherproofing

[Gene K5GS]

UST HDX-572:

I used automotive grease on the exposed anchor bolts / double nuts, that 
was 16 years ago. The base was buried in snow several months each 
winter.   When I took the tower down last May to move it the nuts came 
off with no fuss or stress.

Installed new anchors at the new QTH.  Exposed anchors / double nuts 
sprayed with cold galvanize, non galvanized embedded anchors went in 
bare . No snow and little rain at this new QTH.

The UST specs don't call for coating the embedded anchors, nor did the 
Professional Engineer that inspected the anchors / rebar cage make any 
comments on coating the anchors.

Cheers,
Gene K5GS
