Kinghelm’s KHB(RG113)-100-29 is built with a high-quality RF design. One end is equipped with a precision-manufactured IPEX MHF I (1st generation) connector, ensuring smooth mating, tight fit, low contact resistance, and minimal transmission loss. The other end features a standard SMA female connector with external threads and an internal socket, fully gold-plated to enhance corrosion resistance and conductivity—delivering reliable data transfer in diverse operating conditions.

The cable is constructed with premium black RF1.13 coaxial wire, which has an ultra-fine 1.13mm outer diameter. This ensures excellent signal sensitivity, superior flexibility, and effective EMI resistance, making it ideal for routing through tight spaces or structurally complex devices. A black heat-shrink sleeve provides additional stress relief and strain protection at the joints, reducing the risk of signal loss due to pulling, bending, or vibration.

Compared to shorter variants, the 100mm cable length of the KHB(RG113)-100-29 significantly extends its applicability in intricate system layouts. It is especially useful for bridging across enclosures, between modules, or over power-isolated regions. Its versatility allows for seamless integration in industrial communication terminals, UAV systems, automotive GPS modules, security monitoring antennas, and IoT equipment—meeting both adaptability and signal fidelity requirements in demanding projects.

This product is supplied in a five-piece pouch pack for convenient bulk purchasing and on-site inventory management. Each unit weighs only 3.96 grams, maintaining a lightweight profile that doesn’t add load to the host device. Whether for OEM mass production or engineering prototype development, the KHB(RG113)-100-29 ensures easy handling and rapid deployment. Kinghelm adheres to its core values of “Quality First, Technology Driven,” maintaining strict control from materials to manufacturing to guarantee consistency and performance in every cable.

From a technical perspective, this adapter cable supports wide-band RF transmission, performing excellently across 2.4GHz, 5.8GHz, and even higher frequencies. It remains stable in complex electromagnetic environments, making it an ideal choice across various phases including prototyping, field testing, small-batch trials, and production-scale integration.
