SWR is a direct measurement of impedance mismatch. If you change the
coax length, thereby changing the angle the coax is conducting, and
the SWR changes, then there is something wrong with the antenna itself
that needs to be fixed.

Physics dictates this. There's no way around it.

Coax Length DOES NOT MATTER for a single antenna setup. Period.

I'd only agree if the antenna perfectly decoupled and was a perfect
load for the radio. In other words if everything operated perfectly
in a perfect world.

As far as mag mounts and using a automobiles as a counterpoise ? ? ?
That scenario is not even close to a perfect world.

I often wonder why there is so much criticism when one suggests
using the manufacturers recommended length. This criticism seems to
be followed by the statement that "any length will do". They believe
that 10 feet, 11 feet, 13.5 feet,ect. ect. are fine. Just don't pick
18 feet !!!!!! How hypocritical is that? Isn't 18' also a length
contained within the statement "any length will do"?
