For transmitting, that 10-mile long conductor would be close to an
end-fed full-wave, and perhaps a flame-thrower, for SAQ [17 KHz]. On 20
meters, it would be an end-fed 805 wavelength conductor [wonder how that
would model in EZNEC?], all the power dissipated in the first few
hundred meters of the conductor, and most of the conductor in the far,
far, far field of the antenna that is actually radiating.
Actually, I have the urge to waste a little time, QRX, I'll try it.

I wintered over at Byrd Station in 67-68. The "Long Wire" VLF station was, as I
remember, about 11 miles away from the main Byrd station to get away from noise sources for the
research that was being done. Several of us at Byrd walked out there one day (although I guess it
was night, seeing as how nights were 4 months long). I'm pretty sure the 10 mile antenna was for
receiving but KC4AAD might have used it for transmitting. My own station, KC4USM, used a 700' long
vee beam, on the ice. "Ground" was something like 7000' below, 2000' below sea level.
