This product is a 5.8GHz 5dBi high-gain external antenna with a lead-out cable. It adopts an upgraded composite radiation structure combining copper tube, copper post, and spring—a three-in-one design that ensures structural stability and resistance to deformation. The frequency band is precisely matched for 5.8G high-frequency operation, delivering consistent impedance. Compared to ordinary single-spring antennas, it offers higher receiving sensitivity, lower high-frequency loss, and more uniform and stable signal transmission and reception. The standard 5dBi high-gain design effectively extends the coverage range, wall-penetration capability, and transmission distance of 5.8G high-frequency signals, significantly mitigating common issues such as weak signals, stuttering, intermittent disconnections, and dropped connections over long distances—greatly enhancing high-frequency communication stability.
The antenna is paired with a 1.37 black high-quality coaxial cable featuring a complete shielding structure and excellent EMI suppression performance, effectively isolating interference from internal device circuits and external stray signals, ensuring pure, low-attenuation, noise-free 5.8G high-frequency signal transmission. The cable jacket is flexible, bend-resistant, pull-resistant, and tear-resistant, suitable for internal device wiring and installation in tight spaces, resisting jacket damage or conductor breakage even after repeated bending. The terminal end is equipped with a standard MHF connector, offering precise mating, tight engagement, and stable contact resistance. It resists false connections, loosening, and oxidation after repeated plug/unplug cycles, delivering high connection reliability. The exposed cable length is 165mm with standard, uniform dimensions, requiring no secondary cutting—easy to assemble with consistent batch quality. It is widely compatible with 5.8G wireless video transmission, FPV drone systems, audio/video transmission, smart gateways, and industrial high-frequency wireless equipment for signal enhancement.
