4 Port MCA704/BN 700 MHz Receiver Multicoupler
MCA704/BN 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, 700 MHz service band monitoring,
trunk-tracking, etc.. It can be used in any UHF monitoring platform
using receivers, scanners or spectrum analyzers.
The MCA704/BN 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, 700MHz
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
Choose from one of the two length options for connecting the
multicoupler to the scanner:
RG58 Jumper Cable, 3', BNC Male to BNC Male
RG58 Jumper Cable, 6', BNC Male to BNC Male

EMR Band pass filter
EMR Corp RF Preselectors vary from single or dual
cavity resonator combinations, to mult-stage inductive,
aperature coupled, or combline filters. Special
preselector assemblies may include one or more of
these devices in combination, multiple pass and stop
band characteristics, and special notch elements
according to the complexity of site requrements. EMR
preselectors are designed to optimize loss, selectivity,
and costs; with respect to the particular site
requirements and frequencies.
