7/16

The 7/16 threaded interface connectors have been designed for low intermodulation and VSWR applications in medium to high power transmission systems. Several styles within this range are supplied with sealing rings. Therefore they are suitable for outdoor and tower mounted applications acc. to IP 68 water tightness.

This connector range is suitable for the standard ranges of flexible and semi-rigid cables and is also available in panel mount versions.

The characteristic impedance of the 7/16 coaxial connectors is 50 ohm.

7/16 connectors meet the specification of IEC 169-4.
