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

In high-performance RF systems, air dielectric coaxial cable provides critical advantages through its unique construction that maximizes air volume between conductors. This design delivers the lowest possible attenuation among coaxial transmission media, alongside excellent phase stability and high power handling capacity. Standard implementations feature corrugated outer conductors for flexibility and crush resistance, with pressurization systems maintaining dry internal conditions. These cables find essential applications in telecommunications infrastructure for base station antenna connections, microwave radio relay systems, broadcast transmission installations, and defense communication equipment. A documented use case from a metropolitan wireless internet service provider network shows their deployment in connecting rooftop antennas to base station equipment with path lengths up to 15 km. In satellite communication systems, they form critical links between modems and antenna systems in both uplink and downlink paths. For test and measurement applications, they serve as reference cables in network analyzer configurations. Selection criteria encompass frequency range, attenuation requirements, power handling needs, passive intermodulation performance, and environmental conditions. Our product portfolio includes various air dielectric cable types with different diameter options and performance characteristics. We provide engineered solutions including custom cable assembly, connector options, and technical support for system integration.
