This RF high voltage air variable capacitor is designed for precise tuning in small loop antenna and other RF circuits. Featuring a CW1-270P ceramic single section design, it provides a continuously adjustable capacitance range of 10-270pF, supporting stable performance under demanding conditions. Rated at 1000VDC, this air variable capacitor is suitable for high-voltage RF applications, including ham radio, QRP transmitters, antenna tuners, matching networks, and RF test equipment. The high-quality ceramic construction ensures excellent insulation, low loss, and long-term reliability. With smooth rotation and fine adjustment capability, the capacitor allows accurate frequency tuning and impedance matching. It is ideal for DIY RF builders, experimenters, and hobbyists requiring stable and repeatable capacitance adjustment in compact RF designs. Applications include loop antennas, magnetic loop antennas, LC filters, oscillators, RF amplifiers, and antenna matching circuits. Its compact form factor and robust structure make it easy to integrate into enclosures, tuner boxes, and custom RF projects.
