[TowerTalk] Grounding connection to tower legs

[Howard Hoyt]

Hi John,

The intermediate grounding kits are almost always bolted to lugs on 
galvanized brackets welded to the tower itself.  It is likely that the 
grounding whips provided by Andrew in their grounding kits utilize zinc 
plated lugs on the far end as opposed to the more common tin plated 
lugs. So the interface here would be zinc plated lugs on galvanize, 
which have extremely similar anodic indicies.  I don't see corrosion on 
them as a matter of course...and all grounding from the tower to the 
ground field is done using exothermic welding.

These look very nice if you use copper wire but I do not think they will
work if you use copper strap.

What do broadcast stations use?
