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.


Nobody said it would be any different ,go back and read my post. I was very
clear on why manufactureers say to use 18 ft and why you do not have to.

UNLESS SOMETHING IS FUBAR CHANGING COAX LENGTH DOES NOT CHANGE SWR. JUST THE
IMPEDANCE THE RADIO SEES.SWR IS DETERMINED SOLEY BY THE IMPEDANCE OF THE
ANTENNA AND THE IMPEDANCE OF THE TRANSMISSION LINE.
YOUR STATEMENT PROVES NOTHING.


The only FUBAR is your satements. If you have a matched antenna, and
use a 1/2 wave of coax, you can use any coax impedance you want. Take
a 50 ohm antenna, feed it with a 1/2 wave of 500 ohm coax, the radio
will still see a 50 ohm antenna.
