[BC] Counterpoise Ground System

[Alan Alsobrook]

Right now I'm on limited bandwidth, So I haven't looked at all of Willies pictures, but the link 
below is another version of an elevated ground screen. I want to point out that that's not to be 
confused with a true elevated ground system. I was planning on doing one of those but the situation 
changed and I put in a full standard ground system instead. I was working with William Culpepper on 
that one. One thing to keep in mind on elevated ground systems is that it's just not a case of 
throwing some wires up on poles. The systems are designed with a specific height from ground and 
length of wires to work properly. In my case the Design called for 6 wires @ 22' above ground. Also 
you should be aware that the ends of the wires are NOT grounded and the voltage on the ends gets 
very high, Think KiloVolts.
