yes, the spread in the center insulator does affect the resonance and
current distribution and match and all that stuff... but for typical spacing
changes on hf the effect is small enough that you can normally ignore it.
might as well worry about the effect of capacitance between the larger
conductor of the bolts vs the wire if you are going to worry about the small
spacing change.

hi


i was wondering , currently my dipole is fed via a 5ft section of 450ohm
ladderline. it goes up a pvc mast that i have 2 eye bolts on the top
of ...

i've spaced the eyebots such that they are about the same space as the
latter line conductors , and my dipole wires attach to the eye bolts


in different dipole constructions i've often noted that this center
spacing is often at different gaps, typically larger(coiencidentally ).

so if m spacing was say larger (now i have other than 450 ohm feed i'd
guess

what happens

so my ladder is 450 ohm if my gap is say 2"(think thats 600ohm?) how
does the ohms add"" up

and does this typically increase /decrease loss (antenna/and feedline)

does it alter resonance

does the voltage/current nodes move out?


i got mixed up

thanks
