Those old timey engineers at RCA were way smarter then I am, after all they invented the Smith chart, <cut> But that’s just my speculation, and as my wife will tell you I am wrong at least three times a day and its not even noon yet.
And your wife would be correct.
Phillip Smith, an amateur radio operator (call 1ANB) working at Bell Labs, devised a chart (that bears his name) that even today can help engineers understand the behavior of transmission lines.

Smith also invented the Cloverleaf antenna which has found favor in amateur radio antenna designs over the tears.
