Active multicoupler are designed to distribute antenna signals to multiple receivers without loss and with high isolation between ports. It is specifically suited for signal intercept stations, both fixed or mobile platforms. It can be used in any VLF/HF/VHF/UHF monitoring post using receivers or spectrum analyzers. The devices have a mechanical and electrical design construction that can meet any government, military or commercial specification.

The basic use of the receiver multicoupler is to enable several radios , or scanners, to share a common antenna system. The advantage of using a multicoupler in signal monitoring applications were several receivers are used (such as in SIGINT/COMINT), is in the port-to-port isolation of the coupler. Isolation will reduce the possibility of RF interaction between receivers caused by local oscillators, synthesizers, etc. If an external pre-amplifier, receive filter or lightning protection device is used, only one is needed to service several receivers.

Both passive and active broad-band models as well as narrow-band specialty couplers are manufactured to meet a multitude of HF, VHF and UHF monitoring applications. Standard port configurations from 2 up to 8 are available.  Active models include broad-band low-noise amplifiers, front-end protection, and, depending on model, input High-Pass or Low-Pass filters.
