about 4-8 feet of snow during the winter. It seems obvious that I can't
ground mount the hot side of the vertical because it will get covered up.
SO, I'm going to raise it up by mounting it on top of a steel tube that
runs down into the radial plate. It would look sort of like an umbrella
stand for your outside patio umbrella.

Paul, I have a number of verticals for 160m -> 40m that have the base
covered in deep snow during the winter, and I see no problems at all. I
would not go through the trouble of trying to elevate the base 7' because
of snow.
