Pctel NMO-58UNC NMO58U-NC Mobile Antennas Mount, 1 Thread, 3/4" Hole Mount (NMO)

The PCTEL NMO-58UNC is a professional-grade NMO mobile antenna mount engineered for permanent vehicle installations where a reliable, low-profile antenna foundation is required. Designed around the industry-standard NMO mounting interface, it accommodates a standard three-quarter-inch hole cutout in a vehicle roof, trunk lid, or similar metallic surface, providing a secure and weather-resistant mechanical anchor for a wide range of mobile whip antennas. The mount ships with a generous length of RG58U coaxial cable pre-attached, allowing installers to route the feedline through interior panels and into the vehicle cabin without requiring additional cable extensions in most typical vehicle configurations. Because the connector is not included, professional installers retain the flexibility to terminate the cable end with the connector type that best suits their specific radio equipment and installation requirements. This approach makes the NMO-58UNC particularly well suited for fleet operators, public safety communications installations, utility and field service vehicles, and any professional environment where a clean, permanent antenna mount is preferred over temporary magnetic-base alternatives. PCTEL's NMO mounting standard is widely recognized across the land mobile radio industry, ensuring broad compatibility with antennas designed to that interface.

Key features & benefits
