This product is a 1.88~1.93GHz dedicated frequency band fiberglass high-gain antenna, with overall dimensions of OD20.00 × L254mm. Featuring standard specifications and a neat design, it uses a high-strength fiberglass housing formed in one piece. The housing is sturdy and compact, offering excellent compression and impact resistance while resisting deformation. It also provides outstanding waterproof, dustproof, high/low temperature resistance, aging resistance, and corrosion resistance—capable of long-term stable operation in harsh outdoor environments such as open-air sites, field base stations, and industrial outdoor settings, with weather resistance far exceeding that of ordinary plastic antennas.

Inside, the antenna adopts a dual copper tube + spring composite radiation structure. The multi-layer precision coupling design enables highly accurate frequency matching, with dedicated optimization and tuning for the narrowband 1.88~1.93GHz frequency band. Impedance matching is uniform, RF transmission loss is extremely low, and signal transmit/receive sensitivity is high with strong reception stability—effectively resolving common issues such as weak signals, poor coverage, susceptibility to interference, and dropped connections over long distances in dedicated frequency band communications, ensuring long-term stable device communication.
