7/16 DIN to...
7/16 series is a threaded coupling connector designed for high wattage transmissions, requiring very low VSWR and minimal intermodulation.
The name derives 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 popular in defence, broadcast and other microwave applications.
