CB Antenna Upgrade 2014 Ultra, from J&M
The CB antenna system on the 2014 Harley Ultra, Ultra Limited and CVO Ultra, all suffer from the same issues; insufficient coax cable shielding inside the tail trunk, poor grounding at the tail trunk mounting points to the rest of the frame and very high SWR readings.

it works, therefore it is something that they can tout as a part of their system. it doesn't have to work good. they probably don't use it therefore it doesn't bother them. adequate ground is often a problem with cb's. problem is that the fix is more expensive than some radios. i'm sure its a quality product, as always with J&M but I don't use the CB enough to really warrant the upgrade.

Installed J and M upgrade
I just installed the J and M kit. Not sure that it made any difference. I have the 14 Classic with the upgraded radio and cb added. Took the bike out with a friend who has a 14 limited. Tested the stock set up by having my bike stationary and the other bike going ahead measuring the distance with teh trip odometer. Got 2.0 miles with the stock set up. Installed the J and M kit and retested 2 hours later on the same road. Weather conditions virtually the same. There was no appreciable difference in transmission/reception distance.
The install instructions could be clearer on the installation of the ground wires. The pictures only show the forward frame bolts and not the rear. The cable has three connection points, on different lengths. The instructions don't tell you which leg of the grounding cable should go to which frame bolt. I will call J and M tomorrow to see if I made any mistake in the installation.
