Diamond C110BNC Mobile Antenna Extension Cable 10 ft Low-Loss RG-316 PTFE Coax Mini-UHF (F) to Mini-UHF (M) with BNC Male Termination for HT and Vehicle Antenna Systems

The Diamond C110BNC Mobile Antenna Extension Cable is a professional-grade RF extension lead designed to enhance the reach of your existing Diamond Antenna mobile cable assemblies and mounts. It provides a generous 10 ft (3 m) of low-loss RG-316 PTFE coaxial cable terminated with a mini-UHF male connector and a BNC male connector, allowing you to extend your antenna feed from a Diamond-style mini-UHF feed cable to equipment that uses a standard BNC connection. This configuration is especially useful when you need to route the antenna feed from a trunk or roof mount to the front dash, remote head, scanner, or handheld transceiver with a BNC input. Diamond’s C-series cable ecosystem is known for its high-flexibility RG-316 Mil-spec PTFE coax, which maintains consistent 50 ohm characteristic impedance and excellent signal integrity over VHF/UHF bands while remaining pliable enough to work through vehicle body panels and tight spaces without kinking or degradation. The mini-UHF male end plugs directly into the female mini-UHF connector found on many Diamond mobile cable assemblies such as the C101 or C101NMO, eliminating the need for multiple adapter interfaces and keeping your RF path clean and reliable. At the opposite end, the BNC male connector is a widely used termination for portable equipment, handheld transceivers, scanner antennas, and many BNC-terminated coax leads. This means you can confidently link your vehicle antenna system to a broad range of radio gear without additional adapters, reducing connection points that can introduce loss or mechanical work-hardening over time. Whether you are deploying in a mobile comms vehicle, staging at an event, or supporting field operations, the C110BNC extension ensures your antenna feed reaches your operating position with minimal fuss. The cable’s 10 ft length offers a strong balance between flexibility and reach, giving operators plenty of cable to navigate dashboards, mounts, and routing paths while keeping overall signal loss low. This extension is an excellent complement to Diamond Antenna’s mobile mount ecosystem and is especially suitable where the original cable run supplied with the mount is insufficient to reach the operator or remote head position.

• Extend the reach of your existing Diamond Antenna C-series cable assemblies with a 10 ft low-loss RG-316 PTFE extension specifically designed to connect from a mini-UHF female-terminated mobile cable to a rugged BNC male connector for flexible routing in your vehicle or field setup
• Built with quality RG-316 coax featuring PTFE insulation, this extension cable maintains a consistent 50 ohm impedance across VHF/UHF frequencies, supporting efficient transmit and receive performance between your antenna mount and handheld or base radios with BNC connections without significant signal loss
• The compact mini-UHF male connector mates directly to a mini-UHF female end of Diamond C-series assemblies such as C101 or C101NMO, letting you extend the cable run without adapters and simplifying installations through dashboards, remote heads, or other tight body panel locations
• Perfect for use with handheld transceivers, mobile radios, scanners, or test gear that terminate in BNC connectors, this extension lets you bridge the connection between a vehicle antenna feed and portable equipment while keeping cabling neat and organized
• Ideal for amateur radio, public safety, scanning, and mobile communications setups, this BNC extension cable adds flexibility and reach to existing Diamond mount systems when the supplied cable isn’t long enough to reach your operator position
