This product is a high-performance 4G small mushroom-head external antenna. With a compact, space-saving design, it takes up minimal installation space. The housing is sturdy, abrasion-resistant, anti-aging, and fade-resistant, offering excellent dustproof, moisture-resistant, and weather-resistant properties—suitable for long-term indoor and outdoor device installation.

Optimized and tuned for the full 4G frequency band, the antenna offers wide frequency coverage, precise impedance matching, and high receiving sensitivity. Signal transmission and reception are uniform and stable, effectively enhancing 4G network transmission speed and connection stability—resolving common issues such as network stuttering, weak signals, and dropped connections over long distances, ensuring continuous and efficient data transmission.

The antenna is paired with OD1.13 black double-tin coated coaxial cable. The double-layer tin mesh shielding structure is dense and complete, delivering extremely low RF loss and strong EMI suppression capability, effectively blocking internal device stray noise and external electromagnetic interference to ensure pure, noise-free 4G signal transmission. The cable is soft, flexible, bend-resistant, and pull-resistant, suitable for internal wiring in tight device spaces—resisting jacket damage or conductor breakage even after repeated bending for extended service life.

Both ends of the product feature differentiated precision processes. The P1 end uses a PCB soldering process, providing secure soldering, stable conductivity, and resistance to desoldering—allowing direct attachment to the board for fixation. The P2 end features a precision-crimped MHF-1 PLUG connector, with tight, full crimping, good coaxial alignment, smooth plug/unplug operation, and stable contact—resistant to false connections, pin detachment, and loosening over long-term use.

The finished standard exposed cable length is 80mm with precise, uniform dimensions, requiring no secondary cutting—ensuring consistent batch assembly quality. This antenna is widely compatible with 4G modules, IoT terminals, industrial data transmission equipment, smart security devices, and wireless communication systems.
