Product Overview
The TXGN-JKD-20 is a professional-grade multi-band rubber antenna designed for 2G, GSM, GPRS, and NB-IoT applications. Engineered for high stability, it features a 3.3 dBi peak gain and a pure copper internal radiator (not a common spring structure) for superior bandwidth and consistency. Encased in flexible TPEE material with a bendable design, it is ideal for mobile terminals, routers, and industrial IoT gateways.
