Digital 340-100NM 100' Cable

The Digital 340-100NM 100' Cable is a professional-grade low-loss antenna cable engineered for vehicle communication systems, mobile radio installations, and marine electronics where signal integrity matters. Whether you're upgrading a truck bed CB setup, installing a two-way radio in your work vehicle, or running a marine VHF antenna to the cabin, this 100-foot run demands cable designed to minimize signal degradation over distance. Digital Antenna's reputation in the automotive and marine sectors stems from their commitment to reducing attenuation—the enemy of clean, reliable RF transmission across long cable runs that inevitably occur in larger vehicles and vessels.

This cable's low-loss construction uses quality shielding and impedance-matched conductors to preserve signal strength from antenna to radio head unit without the noise floor creep that plagues bargain coaxial cable. The 100-foot length addresses real-world vehicle applications: a cable run from the roof-mounted antenna down through the frame, along the interior wall, and into the dashboard or cargo area of a full-size pickup, semi-truck, or larger vessel. The specification designation (340-100NM) identifies this as Digital Antenna's standard vehicle-rated coaxial cable product, suitable for frequencies spanning CB radio (27 MHz) through modern UHF and VHF mobile communications. At 2 pounds, it's manageable for single-person installation while remaining robust enough for permanent mounting with proper clips and conduit routing.

Mechanics and fleet technicians installing aftermarket communication systems trust this cable for applications where a single 50-foot run simply won't reach from an underhood or roof antenna location to a rear-mounted radio cabinet. It's ideal for work trucks operating in rural areas relying on CB or commercial two-way radio, emergency vehicles requiring reliable antenna feed, and recreational boaters integrating marine band equipment. Installation best practice calls for UV-resistant cable ties, avoiding sharp bends (maintain a minimum bend radius), and grounding the shield at the radio chassis to prevent RF feedback. The Digital 340-100NM pairs seamlessly with standard marine and automotive antenna connectors, making it compatible with most mobile radio systems already in use across North American vehicles and marine platforms.
