Also known as combiners or splitters, the CF-4160J operates as a band-pass filter, allowing RF signals to pass simultaneously in both directions through its common connector. With its exceptional isolation properties, you can expect a superior level of signal separation between ports.

Dual-band Capability: Effortlessly transmit and receive signals from two radios at the same time into a dual-band antenna. This flexibility allows you to maximize the potential of your communication setup.

Separate Outputs Integration: Merge a dual-band radio with separate outputs into a single dual-band antenna. This feature simplifies your setup and reduces unnecessary complexity.

Single Connector Duplexing: Utilize a single connector duplexed radio and split it into separate antenna systems. This capability expands your versatility and enables customized antenna configurations.

Coaxial Efficiency: By employing a duplexer at both ends of the coax run, you can run a single coax cable to two antennas at the top of the tower and two radios at the bottom. This ingenious design saves you from additional coaxial costs and reduces excessive weight.
