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.
