COMMSCOPE's C-30-CPUSE-N-AI6, 30 dB directional coupler supports indoor and outdoor applications in the LTE 700 MHz cellular/GSM, the PCS/DCS–1800 band, and the 3G band to 2700 MHz. Each unit couples a defined fraction of a high power cellular signal with minimal reflections or loss.

The wide frequency range allows use with multiband antennas, radiating cable systems, and in wireless base stations. The dissipative loss is minimized and reliability enhanced.
