The secondary, or coupled outputs are available in any conventional coaxial connector, or we will design a custom connector to meet your needs.
These couplers offer the utmost in versatility with coupling values ranging from 10 to 70 dB, in any increment. The mainline is equipped with choke or cover flanges, as required.
