High-Quality Air Dielectric Coaxial Cable | Low Loss & Reliable

Air dielectric coaxial cable represents the pinnacle of low-loss RF transmission technology, employing engineered air gaps as the primary dielectric to achieve superior electrical characteristics. This design approach yields attenuation values significantly lower than solid dielectric alternatives, particularly advantageous at frequencies above 2 GHz where dielectric losses dominate. The physical construction typically features a center conductor precisely centered within a corrugated outer conductor through periodically spaced dielectric supports, maximizing air volume proportion. These cables are specified for demanding applications including: metropolitan area network wireless bridges, satellite communication uplink/downlink systems, and high-definition broadcast contribution links. An implementation case in smart grid communications shows their deployment in substation wireless networks, reliably transmitting synchrophasor data with minimal latency. In aerospace and defense, they are integrated into airborne radar systems and unmanned aerial vehicle datalinks. For active antenna systems in modern mobile networks, air dielectric cables preserve signal quality in dense array interconnections. Performance considerations include phase stability under temperature cycling, dynamic bending performance, and passive intermodulation characteristics for multi-carrier systems. Our manufacturing process includes 100% electrical testing, with optional phase matching and PIM testing to -170 dBc. We offer various series optimized for different frequency bands and power levels, with options for low-smoke zero-halogen jackets for indoor applications.
