When it comes to CB antennas, we always think two are better than one. If you’re in the same school of thought as us, make sure you choose the right coax that can accommodate your ant farm. This RG-59 coax cable has a 95%+ shielding rating, which reduces signal loss and improves your transmission range. A stranded center conductor and polyvinyl insulation help the cable hold up against internal shorts and external wear. The cable is 18' long with two terminal ends that are compatible with lug-style studs, and side and ball mounts.

Coax cable

By far the best cable I've ever worked with. It shapes and bends in place with wase. Not stiff like other cables.
