    Protip H3 rear door cb antenna install

    This is not the only way to add a CB antenna to an H3, it has been done before, but this may help with your install when the time comes. If you are going to wheel it, then you just got to have ears!

    What to use:
    K40 (K4018FME) 18' Super Mini-8 CB Antenna Cable with Removable FME Connector;
    Roc Doc H3 Rear Door Antenna Bracket;
    Firestik K-4A Stud (3/8" x 24 threads mount);
    Insulated ground wire with eye butt connectors for each end; and,
    Pan head #8 or 10, " long Sheet Metal Screw.

    I chose the above and mated them with a K40 Electronics 4' Superflex Whip Antenna (SF-400) which is s super flexible 1/4" fiberglass shaft with top loaded tunable coil, Black in color. I found this to be great for wheeling in the trees because I have seen others break.

    The K40 Super Mini-8 CB Antenna Cable has a removable FME style connecter which make installation a breeze, and allows the cable to snake through the H3 rear door flexible wire conduit, and has an exterior weatherproof boot.

    Starting at the rear door, you need an L bracket, and Roc Docs 3/16" press formed rear door antenna bracket was designed exclusively for the H3 and up to the challenge of whatever antenna abuse you can dish out. Our Roc Doc bracket clears 33" and 35" tires no problem and accommodates any 3/8" antenna stud. There are other brands you can choose, but when made from thin white metal, we know they can break.

    Available in Stainless ($19.99) or Painted Metal ($14.99) at

    The Roc Doc Rear Door Antenna Bracket fits over the upper left rear tire carrier eternal torx stud. Remove the spare tire. You need a 15MM wrench for the nut and a 8MM external torx socket to hold the stud (pliers can be used if your tool box has yet to see external torx). Once the nut is off, clean up the stud with an old tooth brush or SS detail brush.
