[TowerTalk] New Tower Grounding Advice

[Red]

Hi, Bill;

In addition to Phil's advise, I'll mention a possible problem if you 
place copper in direct contact with your tower legs; if I recall 
correctly, copper will react with zinc to remove the protection provided 
by galvanizing a steel tower and I know for sure that copper will react 
with aluminum to create an insulating accumulation of aluminum oxide.  
Transition connection devices are available for connecting copper to 
aluminum and may be available for grounding galvanized towers.  They 
should be used with the appropriate anti-corrosion paste materials.  ICE 
offers several anti-corrosion compounds for use in joining various 
materials.

Remove the clamps and wires twice per year to renew the anti-corrosion 
paste and assure that the connections are sound.
