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.
I pity people who can't find laughter or at least some bit of amusement in
the little doings of the day. I believe I could find something ridiculous
even in the saddest moment, if necessary. It has nothing to do with being
superficial. It's a matter of joy in life.
