The RAD-CAB-RG213-40 is an antenna extension cable designed to increase the distance between a wireless module and its antenna. This 12-meter (40 ft) cable is constructed from RG-213U coaxial cable with a durable PE outer sheath and features Type N male connectors on both sides. It operates with a characteristic impedance of 50 Ω across a frequency range of 400 MHz to 5.8 GHz. With a cable attenuation of 0.25 dB/m and a total attenuation of 2.88 dB at 868/900 MHz, it is suitable for applications where signal integrity over distance is important. The cable is rated for an operational temperature range of -40 °C to 80 °C, making it reliable for various industrial and outdoor installations.
