MCA804BN is an active multicoupler designed to distribute antenna
signals to four receivers without loss and with high isolation
between ports. It is specifically suited for signal intercept
stations, both fixed or mobile platforms, 800 MHz service band
monitoring, trunk-tracking, etc.. It can be used in any UHF
monitoring platform using receivers, scanners or spectrum
analyzers.
The MCA804BN has a mechanical and electrical design construction
that will meet any government, military or commercial
specification. This unit is designed to give high performance
results in any radio monitoring post using multiple intercept
receivers. Rugged die-cast aluminum enclosure with a black powder
coat finish is standard, olive-drab green (MIl-841OD) is also
available on request.
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, 800MHz 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.

multicoupler to the scanner:
