[Elecraft] Grounding, Lightning & Attic Antennas

[Ed Cole]

Well...I'm blessed to live in a region with No* lightening activity, so 
generally have ignored doing all the preventative work.

*We hear thunder about once every 4-5 years and see lightening even less 
often.

But winter wind brings static build-up on exposed metal (antennas and 
wires) so isolating sensitive electronics is desirable.  Diode discharge 
in coax lines or outright grounding when not in use.

Apparently a static burst (or power-line surge) took out the ground 
choke in my KIO3A RS-232 I/F a few years ago and also got the IC (fixed 
by K3).  I will install my new KIO3B soon to provide direct USB control 
of the K3 (KIO3A to become spare).

I do use ground rods for safety grounding and noise and computers are on 
UPS.

Phone (internet) and power is buried in my area.
