I've been fighting the SWR on this van since day 1.

CB is Uniden 510XL.

Dodge CV RAM company van (like a dodge caravan) with ladder rack and 2 ladders (12ft and 8ft A-frame fiberglass).
Have tried 2 Little Wil no luck.
This is the current setup.
18' RG58AU coax. PL 259 plug on one end and lugs on the other.
I tested 0 ohm end-to-end on center conductor. 0 ohm end-to-end on outer conductor. center to outer WFO.

New mounting bracket. Mounted to center front of ladder rack. 8 guage wire bonding mounting bracket to side door jam.

4" spring (parking garage access) and a FireStick knock-off

testing SWR with Astatic PDC2 meter. All I have.

With all antenna parts connected. Testing with multi-meter at PL-259.
There is 0 ohm between outer plug and the front door jam. so ground is good.
There is no continuity between center conductor and door jam.

I started SWR on 1 at 2.5:1 and 3.5+:1 on 40.

Now the SWR on channel 1 is 2.4:1 and channel 40 is 1.3:1

Need to get SWR down before installing new Cobra. I know I may need to re-adjust. but if I cant get this one down I don't want to install the Cobra and a K40.

I'm out of ideals.
