That raises the question how to get those calibration files.
Most of us do not have an anechoic chamber to characterize antennas,
much less the other equipment needed for this.
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.
