I have a severly limited capacity for understanding alot of theoritical
presentations. I did read some of Cebik's information, and I still wonder
if the velocity of propagation of the "twin lead" used for the folded dipole
can be ignored. I wonder if the VP of the twin lead is an important
consideration when designing a folded dipole.
If the resonant frequency of a folded dipole is identified as that
frequency where the input (feed point) impedance is R+/-j0, it seems that
the 1/4 wave stubs that shunt the feed point might strongly effect the input
impedance.
I recognize that there is a good chance that my reasoning is wrong. It
may be that the "stubs" that I consider to be shunting the fed point, are
not acting the same as a 'non disipative' stub. But, this is where my mind
could benefit from having some "lab data" which is what I refer to as "real
life" data.

Personal experience testimonials are often unreliable. Modeling data are
often more complete, skillfully designed, well executed, and less
colored by the operator`s opinion, by the right modeler.

One highly educated, experienced, and competent source is L.B. Cebik,
W4RNL. The plain folded dipole is just one of the many antenna types he
has modeled and enriched his web pages with. He compares it with the
common open-circuit single wire dipole in his analysis.

Just search on "folded dipole". Cebik`s web pages will appear near the
top of your list of options. Click on the most likely of your options
and you are there.
