MALDOL CP-5NMO Universal adjustable lip mount, 16’ 6” deluxe cable assembly with NMO/PL-259 connectors. Quality appearance and low loss coax cable assembly. Installs easily in only minutes to virtually any lip on a vehicle: Trunk lids, truck rear doors, SUV and van rear doors, hood lip, etc… Does not damage expensive and/or leased vehicles.

Mount adjusts in 4 planes. The first 18 inches of coax is mini RG-188A/U type allowing easy entry through the weather seal into the vehicle without causing wind noise, water leaks or coax damage. The coax balance is low loss with NMO & PL-259 connectors. The PL-259 connector disassembles for easier routing or to shorten the coax length. Soft rubber pad protects the vehicle paint, 4 large set screws hold the mount firmly in place.
