NC1-3/4 NMO Mobile Radio Antenna Cable – 3/4” NMO Connector 5M RG58 Extension Cable

Characteristic
As a core transmission component of in-vehicle mobile communication systems, this NMO interface antenna extension cable is optimized for high-frequency signal transmission. Featuring an industrial-grade 3/4-inch NMO female connector, it seamlessly adapts to mainstream vehicle antenna mounts. Combined with an extra-long 5-meter RG58 coaxial cable, it effectively addresses the complex wiring requirements of large vehicles (such as trucks and RVs), ensuring signal attenuation within the technical standard of ≤1.8dB/10m@30MHz.

Core Performance‌
The cable utilizes a double-layer shielding structure. The inner layer is a high-purity oxygen-free copper conductor (purity ≥99.97%), while the outer layer is a tinned copper braided mesh, providing 360° omnidirectional electromagnetic shielding. This effectively suppresses signal-to-noise ratio degradation caused by strong interference sources such as the ignition system within the engine compartment. The PL-259/UHF male connector is gold-plated, maintaining a stable contact resistance below 3mΩ and supporting over 5,000 plug-in and unplug cycle tests, making it ideal for off-road racing or emergency communication scenarios requiring frequent assembly and disassembly.

NOTICE

During the installation process, avoid any collisions.

It is strictly prohibited to disassemble the antenna components; otherwise, it may lead to poor antenna performance.

The installation position of the antenna should be free of any obstructions.

When used outdoors, it is necessary to equip with lightning protection facilities.

may contain electronic components. Do not discard them randomly.
