What Is an Air Dielectric Coaxial Cable?

An air dielectric coaxial cable is a type of RF transmission cable in which air serves as the primary insulating medium between the inner and outer conductors. The inner conductor is typically held in position by a spiral or disc-shaped insulating support, allowing most of the space between the conductors to remain air-filled.

Compared with solid or foam dielectric cable designs, an air dielectric cable can provide lower dielectric loss and higher power-handling capability. Corrugated outer conductors also improve flexibility and make the cable easier to install than rigid transmission lines, especially in base station, broadcast and long-distance feeder applications.

Benefits of Air Dielectric Coaxial Cable

The low dielectric constant of air helps reduce dielectric loss, supporting efficient RF transmission and stable electrical performance. This construction also allows air dielectric coax to handle higher power levels than many solid or foam dielectric cable designs of a similar size.

Other advantages include stable impedance, low attenuation, good phase stability and reliable performance over long cable runs. These characteristics make air dielectric coaxial cable suitable for high-power base station feeders, broadcast systems, antenna connections and other demanding RF transmission applications.

Air Dielectric Cable Connections and Installation

In high-power cellular and broadcast systems, an air dielectric cable can serve as an RF coaxial feeder for transmitting signals between RF equipment and antenna systems over long cable runs.

A compatible feeder cable connector should be selected according to the cable size, impedance and equipment interface. Proper connector matching helps maintain stable electrical performance and a secure cable termination.

Near antennas, radio units or other equipment, a flexible coaxial jumper cable can be used to complete the final connection. This helps simplify routing and reduces mechanical stress on the larger main feeder.
