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

Air dielectric coaxial cable represents a premium solution for high-frequency signal transmission, where its air-centric insulation dramatically reduces dielectric losses compared to solid materials. This translates to lower attenuation figures, typically 30-50% better than equivalent foam-filled designs at microwave frequencies, alongside improved power handling and phase stability. The cable construction often employs spiral-wrapped dielectric tape creating air cavities, or solid polyethylene spacers at periodic intervals to preserve conductor alignment. 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.
