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

Optimizing microwave signal integrity demands careful transmission line selection, and air dielectric coaxial cable excels where minimal loss is paramount. Its electrical superiority stems from air's low dissipation factor, yielding attenuation constants as low as 0.05 dB/m at 10 GHz in larger diameters, alongside high temperature stability due to reduced dielectric constant variation. Common implementations feature silver-plated copper conductors with annular corrugated outer conductors, providing excellent flex life and crush resistance. These cables are ubiquitously deployed in satellite communication VSAT terminals, terrestrial point-to-point radio links, and military tactical communication systems. A documented case in offshore wind farm communications illustrates how air dielectric cables withstand salt fog exposure while connecting meteorological sensors to central control units via wireless bridges. In urban small cell deployments, their use in millimeter-wave fronthaul links supports enhanced mobile broadband density. The cables' high cutoff frequency (for dominant mode) enables reliable operation beyond 50 GHz, suitable for E-band backhaul equipment. When integrating these cables, attention must be paid to proper grounding, pressure monitoring systems, and UV-resistant jacketing for outdoor installations. Available options include jacketed/unjacketed versions, different outer conductor materials (copper, aluminum), and custom phase-matching for phased array systems. Our manufacturing capabilities include complete assembly services with rigorous testing for VSWR, insertion loss, and power handling.
