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.

Unfortunately where ground is a question. What the parameters for "ground" is a good question. Snow doesn't look like earth. Anyhow the impedance came out 11470 ohms +j 17880. The horizontal antenna pattern was along the axis with a beam width of 3.8 degrees and a gain of almost 15 db The vertical pattern peaked at 3 degrees and straight up 5 dB down. 73 de Brian/K3KO On 1/12/2018 16:18 PM, Mal Speer wrote: > I don't know much about antennas, but in the late 60s or early 70s I worked > a station on 20 meters with a 10 mile long (long wire antenna). > > That was KC4AAD in Antarctica.
