WWII Raytheon QK-201 Tunable Radar Cavity Assembly

WWII Raytheon QK-201 Tunable Radar Cavity Assembly – Microwave Radar Component for Airborne Radar Systems

Original WWII-era Raytheon QK-201 Cavity assembly used in high-frequency microwave radar equipment. Features precision-calibrated tuning dial, adjustable cavity section, military electrical connectors, and heavy-duty mounting frame. Components such as this were used in airborne and naval radar systems for frequency tuning and signal generation within magnetron and microwave radar circuits. Marked “Raytheon QK 201 Cavity” on the tuning dial assembly. An uncommon and highly technical radar component from the pioneering era of microwave radar development during World War II.
