Comet CK-3NMO5 Deluxe Mobile Mount Cable Assembly NMO to PL-259 16.9 ft Low-Loss Coax with 18 in Easy-Pass RG-174A/U Section for Vehicle Antennas

The Comet CK-3NMO5 Deluxe Mobile Mount Cable Assembly is a professional-grade mobile coax solution designed for NMO-style antennas used in vehicle radio communications. With a total cable length of approximately 16.9 feet, this assembly gives operators the flexibility to position antennas and route coax easily in trucks, cars, SUVs, and other mobile platforms. A key innovation in this assembly is the two-step coax design that begins with approximately 18 inches of mini RG-174A/U coax. This smaller diameter segment is ideal for feeding the cable through narrow weather seals, door gaps, and firewall openings without risk of damage, wind noise, water leaks, or kinks, which can degrade signal quality and lead to premature cable failure. Beyond the initial pass-through portion, the main coax section uses low-loss RG-58/U cable with a nominal diameter of about 0.25 inches, delivering reliable RF performance across common VHF and UHF frequency ranges used by mobile radios. The connectors on either end ensure broad compatibility and secure connections. The NMO mount base provides a stable, standardized interface for a wide range of antennas that use NMO mounts, while the PL-259 male connector mates with many mobile transceiver outputs and mount hardware. The PL-259 connector shell is designed with a reverse threaded barrel, allowing the barrel to remove for easier routing of the coax into tight spaces before reattachment for secure electrical contact. This versatility makes the CK-3NMO5 ideal for mobile amateur radio, CB radio, public safety communications, or any application that employs NMO antennas. It can be used with vehicle lip mounts, permanent hole mounts, or as a standalone cable where a high-quality, low-loss connection is essential. Built to the same quality standards as other Comet cable assemblies, this unit provides dependable performance for everyday use, field deployments, and long-term installations. With its combination of thoughtful design features, robust connectors, and long cable run, the Comet CK-3NMO5 is an excellent choice for serious mobile radio operators seeking a reliable coax solution that simplifies installation and maximizes signal integrity
