Okay so I am tuning my CB antenna and I cannot get the SWR below 3.0. I pulled it all apart today to make sure everything was right and ground down some more paint and did some ohmmeter testing again. Here is what I am using:
Firestik 2' adjustable antenna http://www.rightchannelradios.com/fi...b-antenna.html
Firestik 18' fireRing coax cable http://www.rightchannelradios.com/fi...-with-fme.html
Teraflex Driver's side CB mount www.quadratec.com/products/16180_00.htm
FireRing Compatible stud http://www.rightchannelradios.com/fi...enna-stud.html
SWR Meter & Cable http://www.rightchannelradios.com/sw...per-cable.html
Cobra 9 Ultra III radio http://www.amazon.com/COBRA-MOBILE-C...=cobra+9+ultra
I tested the FireRing coax and the SWR coax and the ground to the middle pin had no connections. The resistance in both connections in both coax wires was just under 1 ohm.
Okay I have put the mount in place making sure that I ground down to metal all mounting locations on the Jeep and the Teraflex mount.
I even ground down inside the fender where the nuts go. All holes are ground down as you can see above. (Even the ones you cannot see)
After I attached the mounting bracket I put the FireRing coax and stud together. You can see in the pictures that the plastic lip of the FireRing connector and the plastic washer on top are oriented correctly to isolate the antenna from the ground.
I then ran a continuity test to make sure there were no shorts or opens using the test below.
No problems came up with the continuity test. The resistance of the ground on my antenna cable to the body (or to electrical ground it is 1 ohm) is 1.3 ohms.
The extra cable that I had I ran back and forth like you would a 12" yarn skein and zip tied it in the middle. There are no kinks in the cable and the cable is routed up through the rubber grommet in the back corner of the driver's side of the Jeep. It then follows the cable harness forward until it comes to the floor and then it goes under the carpet to the center console and exits where the e-brake handle is.
I took it out to a very wide open level space where the nearest anything is about 150 yards away. I balanced it out and channel 1 & channel 40 are equal at just over 3.0 while channel 20 is at 2.1.
Any help would be very much appreciated as I am totally stumped.
