This stainless steel mount locks into any of the stake hole pockets along the edge of a pick-up truck bed. There is no need to drill any holes in the vehicle. The mount can be used on bed rails with protective covers (such as those on the newer Ford Super-Duty trucks). Because of the stud mount configuration on this mount, it can only be used on trucks where there is inside access to the stake hole pocket (from side or bottom) for the coaxial cable to be routed to the mount. In some cases, this might require that the coax be routed through an opening that is too small for a PL-259 connector to pass. In those cases, the PL-259 will need to be installed after the coax has been routed. The mount will easily support heavy-duty antennas up to 4 feet (1.2m) in length.
