SureCall SC-C-6-CB C-Band 6dB Coupler

The SureCall SC-C-6-CB is a 6 dB coupler designed for 5G C-band and other wideband cellular deployments. It’s built to help installers distribute signal more evenly across multiple indoor antennas in a long cable run. This kind of setup is common in offices, warehouses, hotels, and other large buildings where one antenna isn’t enough to reach every corner.

Unlike a splitter, which divides signal equally, a coupler sends most of the signal through to the next device and only taps off a small portion. That’s what makes it ideal for placing antennas in sequence down a hallway or across a warehouse — you don’t lose too much power early on, and each antenna still gets what it needs.

This model passes signal across a wide frequency range from 600 to 4000 MHz, making it compatible with 2G, 3G, 4G LTE, and 5G signal booster systems. It features N-Female connectors, low insertion loss, and durable construction rated for both indoor and outdoor use.

Whether you're dealing with a long corridor, multi-zone coverage design, or trying to extend reach without degrading signal strength, this coupler gives you a clean and reliable way to tap into your booster line.
