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

Air dielectric coaxial cable represents a specialized category of transmission lines where the dielectric consists predominantly of air, either through physical spacing techniques or foam structures that approximate air's dielectric constant. This construction delivers electrical advantages including lower attenuation compared to solid dielectric cables, higher power handling capacity due to better heat dissipation, and improved phase stability. Common implementations feature spiral-wrapped dielectric tapes, polyethylene disk insulators, or nitrogen-pressurized designs for maximum performance. These cables find critical applications in wireless communication infrastructure, particularly in feeder systems for cellular base stations; broadcast transmission systems for TV and radio; and defense electronics for radar and communication systems. A documented use case in a metropolitan wireless internet service provider network demonstrates their deployment in connecting rooftop antennas to customer premises equipment with minimal signal loss. In satellite communication systems, they interface between modems and antenna systems in both uplink and downlink paths. For test and measurement applications, they serve as reference cables in network analyzer setups. Key selection criteria include frequency range of operation, attenuation requirements, power handling needs, flexibility constraints, and environmental conditions. Our product portfolio encompasses various air dielectric cable types with different diameter options and performance characteristics. We provide engineered solutions including custom cable assembly, connector options, and field deployment support.
