[TowerTalk] Bonding Tower Sections

[Red]

Don't put copper in contact with galvanized steel.  It will remove the 
zinc and the steel will rust and may fail.  Clean joints should be 
sufficient.  Conductive anti-corrosion compound appropriate to 
galvanized steel is a good idea.  If you want further assurance of 
continuity, for lightning protection and for RF performance, use 
continuous galvanized fence wire from top to bottom or use insulated 
copper wire attached to the tower legs through stainless steel or other 
appropriate transition material.  Attach those wires to the tower legs 
at top and bottom.
