What I found interesting in the HEBA103 document was that it seemed the
FS measurements were taken at ground level along two compass points. If
I'm not mistaken, the power radiated is spread out over a 3-dimensional
space and from that standpoint, I don't see how improved FS measurements
taken on the near field at ground translate directly into "high
efficiency."
I didn't read the document. Based on my 60+ years old experience in Pete
Johnson's consulting office as a young EE student, I would expect the
determination of efficiency to be based on running a couple of radials
(that is, making FS measurements at increasing distances, and at least
tens of miles) and comparing them with a lab prediction of FS based on
FCC ground conductivity data. I'm pretty certain that's what FCC would
have required to approve the license.
But on this topic, the only think I know **for certain** is that I'm a
mental micro-midget compared to Maxwell.
Same here.
