I answered your original question by saying that the near field due to a
halfwavelength of wire along an antenna with standing waves (like a
co-linear array of in-phase dipoles) was just the same as a halfwavelength
along a wire in an antenna without any standing waves (like a Beverage).


Unfortunately, that cannot be true. The maximum H-field amplitude at a current
null cannot possibly be the same as the maximum H-field where a current null
never exists.

Dear Cec, your nitpicking is inexhaustible and at this time in the morning I
havn't the energy to sort out what you are talking about.

Best to agree to differ, eh? ;o)

I don't see how you can possibly assert that the fields are the same for
a standing-wave antenna and a traveling-wave antenna because they obviously
are not the same. A magnetic pickup at a current null on a standing-wave
antenna will read a low maximum value. A magnetic pickup at the same point
on a traveling-wave antenna will read a high maximum value.
