MCA208 is an active multicoupler designed to distribute antenna signals to eight 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 VHF/UHF monitoring post using receivers, scanners or spectrum analyzers. MCA208 has a mechanical and electrical design construction that can meet any government, military or commercial specification. This unit will give high performance results in any radio monitoring post.
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. These units are designed to meet government and commercial radio monitoring demands as well as the general hobby market. Active models include broad-band low-noise amplifiers, front-end protection, and, depending on model, input High-Pass or Low-Pass Filters.
