So much great information. Did you know the horn antennas of 1955
had a 6GHz gain of 43dBi and were tri-banders? (4+6+11GHz) To get
an accurate radiation pattern measurement the engineers of
yesteryear utilized a pulse measurement technique, which lets you
avoid reflections in your readings!

Looks like AT&T made many of the same site choices the current
HamWAN map has, but decades earlier. I am in awe of what old timey
engineers managed to pull off before I was even born. And it wasn't
just phone calls, they moved television over that network!<br>
