The closest LNBF's are within inches of the sidewalk. Across the sidewalk from the dishes is the fire hydrant. The flag is attached to the hydrant so it can be 'found' after a big snow fall. (so it's not 'hit' when cleaning out around it)
A month ago, had to have scoop tractor come clean around it as the only part seen before then, above the snow, was the flag and top 3 inches (~8cm) of the hydrant. Now melting, slowly, and can make out the sidewalk in the bottom of the first picture.
The mounting is a homemade NPRM that is expandable. The outer legs can slide on the center leg. It now holds up the sidewinder 1.2m and the elliptical (center and right). Just stretched it out from it's collapsed position in the previous sidewinder picture. It forms a "Z" on the ground with the vertical poles at the corners. The end legs are 4ft (1.2m) and the central long portion is ~6ft (1.8m).
The sidewinder dish is just that because it's mount would only allow around 20° elevation as the lowest. Thought of inverted, but that would have collected snow, so sideways for no snow load.
