Anthony, David,

Robert Golka built a reproduction of Tesla's colorado magnifier
TC back around 1980.  It was more powerful than Tesla's
original coil.  It was very close to Tesla's original design
with the ~ 50 foot primary, large diameter secondary, central
extra coil, etc.

Tesla's colorado coil was large, but really wasn't that powerful.
It's longest sparks were about 33 feet or so.  Some of today's
coils such as Bill Wysock's large magnifier, and Greg Leyh's
Electrum TC are actually more powerful than Tesla's
colorado springs coil.

Is my memory faulty (always a possibility), or did I not read that 
Tesla's Colorado Springs coil went to 40 *meters* in spark length 
(not 40 *feet*) the night he also burned up the C. Springs town generator?
For example, in "Tesla" (Cheney & Uth, Barnes & Noble, 1999), pp.89, 
"Bolts of man-made lightning more than a hundred feet in length shot 
out from the mast atop the station. The commotion could be heard in 
the mining town of Cripple Creek, fifteen miles away." I've read many 
other accounts of this event.
I was born and raised here in Denver; my ex was from Colorado 
Springs; I've been to C - Springs to take photos of the various 
different placards put up at Tesla's work site, and all over 
Colorado, so believe me, it's a bit of a drive up to Cripple Creek.
Page 91 of "Tesla" has an interesting photograph. There are three 
brightly glowing light bulbs between two volt?meters in an otherwise 
unremarkable weedy field with some snow. Two visible wires lead off 
to the right and left, laid on the ground. I'll type in what it says verbatim.
    "Caption in Century Magazine, June 1900, reads: "The photograph 
shows three ordinary incandescent lamps lighted to full candle-power 
by currents induced in a local loop consisting of a single wire 
forming a square of fifty feet each side, which includes the lamps, 
and which is at a distance of one hundred feet from the primary 
circuit energized by the oscillator."
    What I wanted to point your attention to is the square geometry 
of the antenna and its dimensions.
    I am not a antenna theory expert. But does this working example 
tell you anything that is useful?
    -- thanks,

    Dave Small
