UHF connector, also known as M-head, is a threaded locking RF coaxial connector. Its core features include: threaded connection: fixed by internal and external threads to enhance vibration resistance and mechanical stability; Coarse central conductor: with a diameter of about 4mm, suitable for high-power signal transmission; Non sealed design: No waterproof capability, should be used with caution in damp or outdoor environments. Interface type: UHF male head (PL259): external thread design, compatible with antenna equipment; UHF Female Head (SO239): Internal threaded interface, commonly used in radio equipment.
