Product Description
The 25arm300-20e-30 is a lead-thru insulator for HF long-wire antenna systems on aircraft. This feedthrough component routes and isolates the antenna conductor through the fuselage skin, connecting the exterior antenna wire to onboard HF radio equipment. The insulator maintains electrical isolation while allowing the antenna lead to pass through the aircraft structure without signal loss or interference.
Installation follows aircraft maintenance manual specifications and antenna manufacturer guidelines, with secure mounting to the fuselage. Used in general aviation and commercial aircraft equipped with high-frequency communication systems.
