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.

Good for you. I bet that if you used 18' you'd get good results also.

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

Near is relative. Anything short of perfect can benefit from using the
manufacturers recommended length.

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...

???rec.radio.cb.........11 meters........27mhz ???

There goes the "magmount theory" as well..

You haven't proven anything other than you are inflexible in your
belief that other antenna installation can't benefit from recommended
coax lengths. Your installations are obviously perfect because you are
perfect and being so you have done everything perfectly with your
perfect counterpoise in your perfect world.

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

No. When it comes to mag mounts on vehicles it most likely means
that you left the fantasy world behind and realize that you live in
the real world where things aren't so perfect.
