WWII U.S. Military Ceramic Feed-Through RF Insulator / Antenna Bulkhead Connector

WWII U.S. Military Ceramic Feed-Through RF Insulator / Antenna Bulkhead Connector

Original WWII-era U.S. military ceramic feed-through RF insulator assembly used in aircraft and radar installations. This heavy-duty component features a glazed ceramic insulator housed in a cast aluminum flange with threaded terminals on both sides, allowing high-frequency electrical signals to pass through bulkheads while maintaining electrical isolation.

Components of this type were commonly used in airborne radar systems, military radio equipment, and high-voltage communications installations where reliable RF isolation was essential. The rugged military construction and original inspection markings make it an excellent addition for collectors of WWII radar, aviation electronics, and military communications equipment.

Condition is very good original surplus with light storage wear and oxidation consistent with age. Ceramic insulator is intact with no visible cracks or chips. Untested and offered as a historical military electronic component.
