The QMA Male to FME Male RF Pigtail Jumper Assembly from Zhenjiang Binjiang Electronic Co., Ltd. is a specialized, high-flexibility interconnect solution designed to bridge modern quick-lock telecom infrastructure with compact, legacy, or mobile RF equipment.
By combining the high-frequency, push-pull QMA male plug with the ultra-compact, threaded FME male plug, and utilizing the extremely flexible and high-temperature-resistant RG316 coaxial cable, this assembly is purpose-built for tight-space routing, internal cabinet jumpers, vehicular communication systems, and GPS/GNSS timing applications.
As a factory-direct wholesale supplier, we eliminate distributor markups, offering OEMs, system integrators, and telecom contractors premium-quality, 100% VNA-tested cable assemblies with full customization capabilities and aggressive volume pricing.
