Just for kicks, I modeled it with a 1/4 wave counter poise up 12' up
from ground. 14 MHz.
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.

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. I don't have the QSL card I got back then,
but was a picture of part of the antenna. I know it was 20 meters, because I
only had a 20 meter antenna. A 3El wide spaced monobander up about 35 feet.
