What would happen if you made the legs of the dipole out of computer ribbon
cable tied together at the feed end and open at the other? Would that be
similar to what you are talking about?

Fan dipole with all the wires the same lengthand closely spaced.
Resistance should be 2) unchanged as others pointed out. Coupling will
cause broader BW like a cage dipole. Unless your antenna conductors are
manufactured to limit variance Impedence in real world will be hard to

Look up CAGE antenna. It is an old design that reduces the Q of the antenna and
therefore makes the antenna work over a larger frequency range.

I am in the midst of analyzing a Ham market HF antenna.
I'm no engineer, but my guess is the individual DC resistance of each wire
will not change one iota; therefore, the total DC resistance will not
change, either. Then, continuing my guess and ignoring non-resistive
impedance, any RF energy introduced at the feed point will be dissipated
equally
Interesting antenna.
Off the top of my head, at RF, I’d say there’s no difference in the resistive
component of impedance; you’re still talking about a 5-ohm material. The
reactive component probably does have to be modeled.
The big issue I see is that, unless all the component wires are
I am in the midst of analyzing a Ham market HF antenna. Still building the
EZNEC model, but working it thru the gray matter.
Case: Take a 1/2 wl dipole antenna -- center fed. Each side is made up of
multiple, equal length wires that are each insulated, parallel, and closely
spaced. The wires
