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

Engineered for excellence in high-frequency signal transmission, air dielectric coaxial cable leverages air's optimal dielectric properties to achieve minimal signal attenuation and dispersion. The design philosophy centers on creating stable air pockets between conductors through precisely positioned dielectric spacers, resulting in typical velocity factors of 0.88-0.95 and superior temperature stability. These cables are characterized by their low capacitance per unit length and high impedance uniformity, making them ideal for phase-sensitive applications. Deployment scenarios include cellular network infrastructure where they connect base station antennas to remote radio heads, microwave radio relay systems for long-distance communications, and satellite ground segment equipment. An installation example from a cross-border telecommunications project shows air dielectric cables maintaining signal quality across international microwave links operating in 6-38 GHz bands. In railway communications-based train control systems, they ensure reliable signal transmission along trackside networks. For active distributed antenna systems in large venues, they minimize loss between headend equipment and remote units. Specification considerations include operating frequency band, average and peak power requirements, passive intermodulation performance, and environmental protection class. Our manufacturing capabilities include custom cable design, precision connector attachment, and comprehensive electrical testing. We offer various product series optimized for different application environments, from temperature-stable versions for extreme climates to flexible designs for tight spaces.
