It was written by BL&E that
120 radials work,

2, 15, 30, 60, and 113.

No discussion whatever of 120.

There might not have been much "discussion" though it is mentioned, but
the summary does contain the following:

"It is also found that a ground system consisting of 120 buried radial
wires, each on half wave long, is desirable".



I stand corrected.. thanks..
So they extrapolated to 120 as a "nice round number" for the future
purposes of the FCC.

It does appear that if someone blessed the number 120, it was probably
BL&E who did it, even if they were talking about half wave radials.
