4G antenna

This 4G LTE rubber duck antenna is a compact, flexible omnidirectional antenna designed for high-performance wireless connectivity across a wide range of cellular-enabled devices. Engineered to support 4G LTE, 3G, and 2G bands, it ensures reliable data transmission and voice communication for applications such as industrial routers, IoT gateways, vehicle telematics, portable hotspots, and surveillance equipment.

The antenna features a flexible, durable outer jacket made from high-quality TPE (thermoplastic elastomer) or PVC, allowing it to bend without damage while maintaining its shape. This makes it ideal for environments where the antenna may be bumped, moved, or installed in tight spaces. Internally, a precision-tuned helix radiator delivers stable impedance matching at 50 Ω and consistent omnidirectional radiation, minimizing signal dropout and maximizing coverage.
