Firestik CB coax is a great quality choice for general CB installations. The RG-58 coax cable has a 95%+ shielding rating, which reduces signal loss and improves your effective transmission range. A stranded center conductor and polyvinyl insulation help the cable hold up against internal shorts and external wear. This Firestik K8 coax is 18' long and has a terminal end for connecting to lug-style studs and to side and ball mounts.

No breaker-breaker 18 for a radio check

I only buy quality stuff for my communication systems and the coax fits the description.

Coax was thinner than expected. Is working just fine. Speedy shipping as usual here

Good cable, but...

I was hoping it was preassembled to hook to the ball kit for the 102 inch whip antenna kit. I had to splice the wires and attach the appropriate connector for it to work.

Great product and shipped fast

Good for the kit I got

I ordered a kit which this came in and I was happy until I went to assemble it. The kit for Silverado 1500 with the offset pocket stake mount does not fit the firestik 18’ cable. Unless you get rid of the washer, lock washer and the isolator you cannot put the kit together
