However, that raises a good questions, in terms of cones and shedding
snow. I wonder how a straight slender vertical pipe with capped end
would work. Say 6 feet long. Let the snow build on the top. You might
loose a few degrees of sky view above it, but how detrimental would that
be?
Unless you live directly under the path of one of the orbits, satellites
will not pass directly above you, so there would be little los.
But the pipe is not such a good idea. All signals from high elevation
angle will have a long path trough the pipe, changing their phase
ever so slightly. How much, depends on the pipe, it's thiknes and material.
Whether it actually matters or not, depends on your requirements.
You naturally use calibration files for your antenna to compensate for
pseduo-range errors due to azimuth and elevation if you care to that level.
It's just one of several corrections you do if you care about precision.
