Air Variable Capacitor 20-260pf, Measures 30mm x 60mm, CA-293, Used / Surplus

Elliott Electronic Supply has a great selection of Vintage Air Variable Capacitors. These capacitors were commonly used in early radio, Amateur Ham radio, and RF applications. Vintage air variable capacitors are tuning components that use air as the dielectric between interleaved, meshing aluminum or brass plates. These components are sought for restorations and hobbyists for their robust, often "girder-frame" construction and high-quality craftsmanship from manufacturers like National, Hammarlund, or E.F. Johnson. Structure: Features a shaft-driven rotor with interleaved aluminum or brass plates, often housed in a sturdy girder-frame construction. Function: Designed for precisely tuning resonant circuits, such as radio receivers, transmitters, final plate tuning, or antenna loading. Construction: Typically features high-quality materials, such as ceramic insulation and metal plates, providing durability and a classic aesthetic. Types: Available in single or multiple (dual/triple) gang, allowing multiple circuits to be tuned simultaneously.
