[TowerTalk] Screw Anchors

[Pat Barthelow]

Folks:
Appreciate the discussion about screw anchors/deterioration... Now I have an 
idea/possible reason for the strain insulators that are always on the power 
company's guys.  At first I thought it may be some sort of safety to 
guarantee that some power company faults will not dangerously energize the 
bottom of the guy, with associated human hazards.  Maybe another reason is 
breaking a path  for electrolysis currents travelling from the anchor up to 
other, different potential points that would be connected to the guy, save 
for the inline insulator.  If that is a valid reaon, then that would also 
speak to the utility of strain insulators in any ham installation, not only 
for limiting RF influences of guys on antenna pattern   Is an insulation 
break in a guy, a wise idea for purposes of limiting electrolysis currents?
Tnx
