[BC] Counterpoise Ground System

[Dan Kelley]

Years ago while working at KTRC, then 1400 in Santa Fe, NM -
they had an interesting counterpoise coming off a self-
supporting tower located downtown.  The ground system expanded over a 
single story rooftops over a city block that the tower was in the
middle of.

I think the tower is still there - but with the AM now
diplexed off another AM in town, I doubt the counterpoise still
exists.

Has anyone have a Counterpoise Ground System on their AM tower?  Last
month in Radio Guide, Ron Nott brought up some interesting comments in
his article about it, and how it may be the answer of getting away from
the traditional 120 buried copper radials that the commission demands we
AM guys have.

We just had a house across the street from my station that had their
plumbing system redone in copper. The copper thieves came during the
night and yank out all the copper and I guess cash it in for something
like drug money.

If anyone has any pictures of a Counterpoise ground system, please email
them to me. Also I'm sure if you decide to use such a ground system, a
proof of performance has to be conducted to meet efficiency.
