The coaxial cable connected to the KA-131 is fitted and matched at the original time of manufacturing.  The cable and antenna are aligned as a single unit for minimum SWR. A tag stating this requirement is attached to the antenna however it may become detached at some point in the life cycle of the antenna. A label was placed on the antenna as well stating to not alter the cable. The cable is safety wired onto the antenna to further prevent someone from removing the cable from the antenna.  Please see images for refernence.
