Constant-impedance 50 ohm RF connector (75 ohm versions exist) Threaded, O-ring-sealed - weatherproof and vibration-resistant Low loss and clean match to ~11 GHz High power handling (hundreds of watts) Preferred for 70 cm, VHF/UHF weak-signal and microwave Crimp or clamp versions for LMR-400/RG-213 etc.

Strengths

True 50 ohm through microwave; weatherproof; high power; the standard for UHF+ and outdoor use.

Weaknesses

Costlier and bulkier than UHF; needs correct body per cable; assembly is fussier than PL-259.

Verdict

The connector to use above 2 m and outdoors - Type N's constant impedance and O-ring seal make it the go-to for UHF, microwave and tower work.

The Type N is a constant-impedance 50 ohm RF connector with a threaded, O-ring-sealed body that stays clean to about 11 GHz and handles high power. Weatherproof and rugged, it is the right choice for 70 cm and up and for outdoor/tower connections.

Compare the HF-standard UHF PL-259; install it on LMR-400.
