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

Optimizing high-frequency RF transmission systems often necessitates air dielectric coaxial cable, where the strategic use of air as the primary insulating medium delivers unparalleled electrical performance. This approach yields the lowest achievable attenuation among coaxial designs, excellent phase stability, and high average power capacity. Construction methodologies include helical polyethylene supports, periodic dielectric spacers, or microporous PTFE structures that maximize air volume proportion. These cables are essential components in telecommunications infrastructure for base station antenna feeding, microwave radio relay networks, and satellite communication ground equipment. An implementation case from a cross-country microwave system illustrates their use in connecting multiplex equipment to parabolic antennas across 50 km hops with minimal intermediate amplification. In public safety radio systems, they ensure reliable connectivity between base stations and elevated antennas in critical communication networks. For scientific applications like radio telescopes, they deliver signals from cryogenically cooled receivers to processing units with negligible added noise. Performance parameters of interest include frequency-dependent attenuation, voltage standing wave ratio, phase matching tolerance, passive intermodulation characteristics, and temperature operating range. Our manufacturing process includes rigorous quality control with 100% electrical testing to ensure consistent performance. We offer customization options for specific applications, including different outer conductor materials, jacketing options, and connector interfaces.
