Explain this, then... CB radio in my Peterbilt, with a mirror mounted
Hustler HQ-27 on the driver's side.. 6 feet of coax shows a 1:1 on 19,
1.1:1 on 1, and 1.1:1 on 40... 12 feet of coax shows the same
readings... 18 feet of coax shows.. guess what? the SAME RESULTS.

IT IS possible to get near "perfect world" results with a little work,
and attention to detail.

By the way, I've gotten similar results on two meters with a magnet
mount 5/8 2M Lakeview whip on my old Ford LTLA9000. Had to shorten the
coax because I was sick of the bundle of it in the cab... no change in
SWR over a four MHz bandwidth...

There goes the "magmount theory" as well..

If changing the length of the coax changes the SWR, then there is
something wrong with the antenna.

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"?
