Cavity Coupler Rangeful CC8 698–2700 MHz N-Female, 8 dB

The Rangeful CC8 8 dB cavity coupler with N-female connector is a passive RF component for unequal distribution of cellular and broadband signals across 698–2700 MHz. It provides a defined 8 dB attenuation on the side output to produce a weaker signal relative to the main line, enabling controlled splitting or combining of signals in repeater systems, base stations and other RF setups.

Advantages

The CC8 offers a stable, repeatable 8 dB coupling value over a wide frequency range (698–2700 MHz) and supports most GSM, 3G and 4G bands. Its compact cavity design simplifies system integration, helps maintain consistent signal levels when splitting or combining lines, and uses an industry-standard N-female connector for easy connection to coaxial cables and equipment.

Suitable for

• Split signals to two indoor antennas where one area requires a stronger signal and the other a weaker signal
• Compensate for unequal cable losses when antenna feed lines have different lengths
• RF distribution topologies with multiple branches from a main feed in repeater or coverage systems

Key specifications

How to use

Install the CC8 inline between the main feed and the branch feedlines using compatible N-type connectors and appropriate coaxial cable. Orient the main line and side output according to your system topology so that the main line carries the stronger signal while the side port provides approximately 8 dB lower level. Use this device when splitting signals to areas of different size or when compensating for longer feed cables to equalize received signal levels.

Usage recommendations

Place the coupler as close as practical to the distribution point; verify connections and cable integrity to minimize additional losses. After installation, measure signal levels at both outputs and, if necessary, adjust antenna placement or cable lengths to achieve the desired coverage balance.
