7/16 series connectors are a threaded coupling connector designed for high wattage transmissions, requiring very low VSWR and minimal intermodulation. The name is derived from the inner and outer contact dimensions - 7mm OD inner contact, 16mm ID outer contact. You'll commonly find 7/16 DIN connectors on 1/2 and 7/8" feeder cables connected to LTE and WCDMA base station antennas. 7/16 connectors are also popular in defence, broadcast and other microwave applications.
