Yep, the term was known when I became KN6DGW in 1953, but somehow no one
cared. Standing waves were sort of benign, you ran your transmission
line [often 300 ohm open-wire, or TV twinlead] to the 2 or 3 turn link
and adjusted it inwards until your TX was "loaded" to rated input
power. Standing waves formed the basis of "Lecher Lines" used to
measure frequency [well ... wavelength] generally for VHF and above.
Standing waves just didn't create the heartburn that they seem to
today. Granted, today's TX are comfortable with 50 ohms and not much
else but that's just impedance matching networks.
