[TowerTalk] Discharge with a dipole

[K0DAN]

Correct.

In addition I just sent Tony & a few others pix of my sparkplug + resistor 
bleeder kludge. None of this is my invention, nor magic, just copying other 
people's good ideas. Also not guaranteed to protect you from The Big One, 
but will help bleed off charges. If you want some ideas, I'll be happy to 
forward the email + photos to others since the reflector does not support 
attachments. Email me off list if interested.
