Re: [TowerTalk] Verticals and well pipe grounding

[Donald Chester <k4kyv@hotmail.com>]

If the tower is being used as a vertical radiator and a substantial radial  
system is installed, the radials themselves also make the best  lightning 
ground.  By "substantial" I mean at least 15 or so eighth wavelength or longer; 
one or two radial wires regardless of length will offer little lightning 
protection OR RF ground effectiveness. Due to its nature as a short-duration 
pulse, lightning acts more like RF than like DC or 60~ a.c., and lightning 
grounds should be designed accordingly.
