Wilson 2000 help

Did you check your grounds? Is there an open circuit between the center conductor of the cable and the shield? What are you measuring resonance with?

What's the resistance from the antenna mount to your radio ground wire?

 

Well, your coax seems to be fine. Are you using the internal SWR meter? I'm assuming it's a Cobra 29LX, I have one and used the same antenna with the same results until it was properly grounded with 18" or less lengths of braided grounding straps. On mine, the internal meter was inaccurate as most are so I purchased an external meter (around $20) and found it to be very useful on multiple antennas. I'd go from there and work your way through the system. If you can, run your radio power wires (not your antenna ground) directly to your battery with an in-line fuse for added insurance. With the straps ground from the mirror mount to the top hinge of the door then from the bottom hinge to the body and from there to the frame. There are much more experienced people on this forum than myself, hopefully they will chime in(Rabbi's a good one)!

 

It's kind of hard to troubleshoot without an antenna analyzer. If there's no resonant frequency, there's most likely a ground problem. An swr meter can only go where the radio goes.

 

Just for heck of it I would try a different coax cable. No need to properly route it, this is just a test

 

At what point does X=0?
What's the impedance at resonance?
SWR means nothing.
