Description

C-Band Coaxial Directional Coupler manufactured by Narda. This is quite an old piece of equipment but it still works perfectly.

Narda calls it a Coaxial Directional Coupler, but to us it looks much like a Cross-Guide Coupler. Based on the frequency range of C-Band receive of 3.7 to 4.2 GHz it was designed to monitor the receive link from a C-Band LNA.
