The CB antenna system on the 2014-2018 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.
This condition causes poor modulation and limited transmission distance when communicating over the factory installed 40ch CB radio.
Our CB antenna system upgrade kit for the 2014-2018 Ultras includes a custom made RG-58 coax harness replacement, to plug into the coax cable female jack under the back of the seat, then routes to the rear & connects to the CB antenna stud at the inside back of the trunk and the coax shield grounding spade to the metal trunk mounting plate in the bottom, under the inside trunk liner.
Also included are twin braided, hand soldered, copper grounding straps to connect to the underside tail trunk mounting studs, the rear portion of the frame and the frame mounting studs forward of the battery, as the Harley Ultra frame is split right behind the battery.
These easy to install coax pieces and grounding straps will dramatically improve the performance of your CB radio.
This custom kit is manufactured at our shop in Tucson Arizona USA using only high-grade copper coaxial cable, braided copper ground straps, & heat-shrink wrap for maximum durability and performance.
Includes detailed installation instructions.
