Charlie do you have spark gaps on the line?  Like a couple of close spaced 
sparkplugs mounted on a piece of metal with that grounded.

I have used a large knife switch for years at the ladder line exit point on 
the house  to disconnect the line and ground it.  I am having to re route 
everything and now my knife switch if used, would not be easily accessible 
unless I leave a ladder against the house.  Anybody use the large air 
conditioner type contactors, or larger open frame relays for this?  Due to 
contact proximities, will it just flash over anyway, so forget it? My only 
other option is to disconnect the ladder line in the shack but that would 
leave the potential for flashing over inside the house.
