    Do you get RFI? I have a 2011 Rubicon JKU with ATS120 and FT-857D and my swaybar disco, air bag and engine lights comes on everytime I transmit in 20 and 40 meters.

    • Octavio,

      I have not encountered that problem.

      Here are a few thoughts:

      1. Is your radio directly connected to the battery? If you run power through the fuse box, you open yourself to a lot of “intermod.”

      2. Do you have ground braid? The lack of a good chassis ground can cause problems such as the ones you describe.

      Finally, I would check the ATAS-120 to make certain it has good ground on the controller cable. I have a problem with spark plug noise getting into my receiver through the control cable.

  2. Have you seen the Accessories Unlimited AUJ1 CB mount? It uses an existing fender bolt to mount, but also has provisions for installing 4 additional sheet metal screws if desired. I don’t think it’s necessary though. It’s contoured to exactly match the JK’s tub, and RG-8X or LMR-240 will perfectly fit the space between the hood and the tub. Also, the AUJ1 is a rounded mount vs a rectangular/square mount such as the one in your pictures. It’s a little lower profile, not as sharp of an edge, and less likely to catch on something. The mount is meant for CB antennas, so I had to drill the hole out to 3/4″.

    I posted a comment on another of your posts re: LMR-240 vs RG-8X. Looking forward to hearing what you have to say about why you chose one over the other (I went with LMR-240 UltrFlex).
