FireStik 9-Foot and 8-Foot Fire-Flex Coax Cable with FireRing connectors for CB antennas. The FireStik Fire-Flex cable assemblies are manufactured from RG-58A/U Fire-Flex coaxial cable and are designed for use with single antenna installations. Fire-Flex coaxial cable is perfect for CB, scanner, 2-meter, and 10 meter mobile antennas.

The Fire-Flex single antenna coax features FireStik’s exclusive FireRing connector. The FireRing connector is a low profile antenna connector that eliminates the need to install a separate coax ground. The FireRing terminator is a weather tight, trouble free connection that eliminates potential shorts in the coax at the antenna stud.

The 9 foot version of FireStik’s Fire-Flex cable has a pre-attached PL259 connector. The 18 foot version has an unprocessed end. The unprocessed cable makes it easier to route coax through tight spaces, such as automotive firewalls. Soldering is required to attach the included PL259 connector for the 18 foot cable.

The termination of FireStik’s 18 foot Fire-Flex cable is designed to fit any 1/2" (13mm) hole and has a built-in nylon shoulder washer to keep it centered and short free. If you are wanting the convenience offered by this FireStik cable, but do not want to solder your own PL259 end, then use MU8R18 which has PL259 on one end and a FireRing connector on the other already soldered in place for hassle free installation.

CB World also stocks FireStik’s FireRing coax cable available with an antenna stud.

The fire ring cable, firestik antenna , connector and hood mount made the installation easy and worked great. The shipping was much faster than I expected. Super people to deal with. Thanks
This product was a time saver and great product. Fast service and I would buy from CB World again. Thanks, Terry, Houston Ms
Nice cable with durable connectors - just the right length. Works great. Will likely purchase a second one for another setup. Timely delivery and good price.
I recently hooked up a fender mount on my Dodge pick up and the MU8R18 was a great addition to the antenna. I already had a small whole in the firewall and the coax fit right thru it and screwed the end on and hooked up to radio, it was great! I have since bought a extra cable just to have it around..
I purchased this cable to wire a fixed mount antenna set up on a Honda VTX 1300. The cable was perfect for this application with only a little extra length when running from the front to the back. I used the K4R FireRing stud mount and an RP3 3 foot antenna to complete the project. Service from CB World was outstanding and prompt.
This is a nice coax cable well made and it was easy to install after someone told me how to put it on because there were no instruction. Very good quality set up.
Very fast service. Installed and working great. Didn't need to tune antenna, as it was right on with SWR meter.Thanks for such great service. I'll be back with any other CB needs.
This is a nice well made producl. Good instructions.
