The KLK0237 is a high-performance omni-directional outdoor antenna designed for 868 MHz operation, ideal for LoRaWAN, IoT, and other industrial or wireless communication systems.

With a 9 dBi gain, collinear dipole array design, and vertical polarization, this antenna provides stable, long-range signal transmission. Its fiberglass radome and stainless steel/aluminum mounting hardware ensure durability and resistance to harsh environmental conditions.

The KLK0237 offers excellent mechanical strength (IK08) and wind resistance (up to 150 MPH), as well as IP67 waterproof protection for reliable outdoor operation. A built-in DC short lightning protection safeguards connected equipment against static discharge and lightning effects.

The kit includes a tilt and swivel mast mounting bracket, waterproof sealing tape, and a 1 m coaxial cable with N-male connectors on both ends.
