traveling wave antennas;

real traveling wave antennas;
4. the guru denounces real traveling wave antennas as being
non-ideal.

Anyone following this thread knows that the above is absolutely
false. It is akin to dismissing lossless line analysis because
lossless lines don't exist in reality.

It is true that most real world standing wave antennas also
possess traveling waves. When an antenna is 90% standing waves,
the current on the antenna is primarily standing wave current
with a phase that changes very little end to end. The traveling
wave current is almost invisible.

Richard is either very confused himself or deliberately trying
to confuse others. Each reader can decide for him/herself.
