Don't want to argue, Tom. I just want you to make a posting that
contains some iota of technical content. My ten-year-old grand-neice
could easily have thought up your last dozen (mostly ad-hominem) postings.

I know there are people in the past who have
attempted to characterize antennas as transmission lines. It's an
old, hoary method. You have a copy of Balanis. He has references you
can look up to see how close your ideas are to the truth.

Since you brought up Balanis, here are some quotes from Chapter 10 of
his book that should impress you:

"The sinusoidal current distribution of long open-ended linear antennas
is a standing wave constructed by two waves of equal amplitude and 180
deg phase difference at the open-end TRAVELING IN OPPOSITE DIRECTIONS
along its length" page 488 (emphasis mine)

"THE CURRENT AND VOLTAGE DISTRIBUTIONS ON OPEN-ENDED WIRE ANTENNAS ARE
SIMILAR TO THE STANDING WAVE PATTERNS ON OPEN-ENDED TRANSMISSION LINES."
Page 488 (emphasis mine)

"Standing wave antennas, such as the dipole, can be analyzed as traveling
wave antennas with waves propagating in opposite directions (forward and
backward) and represented by traveling wave currents If and Ib." page 489

Uhhhhh Tom, following Balanis' direction is EXACTLY what I have been doing.
Since you disagree with Balanis, it appears that you have never cracked
open his book. I, OTOH, have attended Balanis' antenna classes at ASU
and worked hand in hand with him on a joint Intel-ASU project.
