You didn't state the mass and construction of the UFER ground.
Typically, more than one ground rod per leg is used unless the UFER is
quite large.
It's quite difficult to get the bottom coax grounding, at, or below
grade. Moisture, soil, water, and/or, snow may dictate the necessity of
mounting said grounding somewhat above grade. My bottom grounds are
about 6" above grade which often puts them as much as 2' below the
surface of the snow.
Because there is so little loss at HF, I prefer to use thoroughly
weatherproofed bulkhead connectors for grounding the shields. Each one
adds up, but even with as many as 10 connectors, the loss is still
minuscule.
