[TowerTalk] Spark Gap on an insulated tower

["T Gahagan" <tgahagan@imt.net>]

I recently erected an 80' base insulated Rohn  25G tower.  It is guyed with 
philystran cable.  I have been told that I should install a spark gap at the 
base insulators.  If this is the case, what should the gap be for such a 
spark gap?  I currently have 2 brass straps 1.5" wide X 1/4" thick from the 
top and bottom of the insulators.  The gap is 3/16" wide.  Any advice is 
greatly appreciated.
