The Firestik K8R18 is a high quality RG58 coaxial cable with a Fire Ring connector on one end , and a PL259 connector on the other.  This coax cable can only be used with the K4R stud mount or equivalent due to the Fire Ring connection.  The Fire Ring connection is one of the easiest to install and by far the best connection between your antenna and mount available.  The stranded center conductor makes routing the Firestik K8R18 very easy due to it's high flexibility.  To protect against RF loss and other signal loss issues, the Firestik K8R18 has 95% shielding between the vinyl insulation around the center condutor and the foil shield beneath the outer sheath. The PL259 to connect to your CB radio is included but not installed.  To finish the connection, you must solder the PL259 to the end of the coax cable.


The K8R18 coax cable attaches to your K4R Fire Ring stud mount and the PL259 attaches to your CB radio.  The PL259 is not installed, so you need to solder the PL259 on when finished routing.
