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 configuration delivers the lowest possible attenuation per unit length among coaxial transmission media, alongside excellent phase linearity and high average power handling. Standard designs utilize annular corrugations for flexibility and crush strength, with pressurization systems maintaining dry internal atmosphere. These cables find essential roles in telecommunications infrastructure connecting antennas to base station equipment, in broadcast engineering for transmitter-to-antenna runs, and in test & measurement setups requiring reference-grade transmission lines. Documented use cases include their implementation in radio astronomy observatories where they connect receiver front-ends to backend processors across hundreds of meters with minimal noise temperature increase. In urban 5G millimeter-wave deployments, they serve as interconnects between radios and antennas at street level cabinets. Military applications include tactical communication systems and electronic countermeasure equipment. Specification parameters encompass frequency range, attenuation limits, VSWR performance, power rating, operating temperature range, and bending characteristics. Our product portfolio includes multiple air dielectric cable types with different diameter options (e.g., 1/2", 7/8", 1-5/8") to balance performance and mechanical constraints. We provide complete assembled solutions with connector options including DIN 7-16, N-type, and 4.3-10, tested to meet industry standards.
