This product is a high-sensitivity internal gain antenna, featuring an upgraded copper tube + copper post composite radiation structure. Compared to ordinary single-copper-tube or single-spring antennas, it offers more precise frequency matching, higher impedance consistency, stronger signal receiving sensitivity, and uniform, stable signal transmission and reception—effectively enhancing device wireless coverage, wall-penetration performance, and long-distance communication capability. It effectively resolves common issues such as weak signals, network stuttering, dropped connections over long distances, and signal drift, ensuring long-term stable device communication.

The antenna comes standard with OD1.13 black double-tin shielded cable. The double-layer tin mesh is tightly woven with a full, dense shielding layer, offering excellent EMI suppression capability. It effectively isolates internal device high-frequency stray noise and external environmental interference, significantly reducing RF transmission loss for purer wireless signal transmission with lower attenuation.

The black cable jacket offers a solid feel with excellent flexibility, bending resistance, pull resistance, and aging resistance. It is suitable for complex internal routing and tight-space assembly in devices, resisting jacket damage and conductor breakage even after repeated bending over long-term use, with long service life and consistent batch quality.
