The 503-2021 Jumper Cable series featuring RG214 and RG223 coaxial cables delivers exceptional performance for wireless telecommunications infrastructure requiring reliable RF signal transmission. Engineered with 50-ohm impedance and operating frequencies up to 11 GHz for RG214 and 12.4 GHz for RG223, these jumper cables provide high-quality transmission with minimal signal loss across mobile network applications. The plenum-rated, halogen-free construction ensures compliance with stringent fire safety regulations while reducing toxic emissions. Both cable types offer low SWR characteristics and maintain 66% velocity of propagation, making them ideal for base station antenna connections, DAS installations, and indoor wireless systems. The flexible, lightweight design simplifies installation in confined spaces with bending radii as tight as 25mm for RG223 and 40mm for RG214. RoHS compliant construction meets environmental standards while delivering the robust performance telecommunications professionals demand for mission-critical wireless networks.
