| Multicouplers
- General Description |
|
| 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
most government, military and commercial
radio monitoring demands. Active models include broad-band
low-noise amplifiers, front-end protection, and, depending on model, input High-Pass or
Low-Pass Filters. Please contact
factory for options. TNC connectors are available as an option on all
ports, or, TNC connector on input port and BNC on all output ports.

Power
Supply Notes - Active Multicouplers |
|
|
All Active Multicouplers
requires +12 VDC/100 mA (nominal) to operate. Because of internal voltage
regulation, this input DC voltage may be between +10 volts and +17 volts. DC power is
applied via a standard coaxial style power jack (5.5mm/2.1mm) with the
center pin positive.
For the North American market, a wall adapter
(110VAC/+12VDC) is supplied as a standard accessory. For other countries, using AC power
standards of 220 Volts, a DC power plug is supplied for the DC connection, this plug must
wired by customer. On request, we can supply this plug wired with about 6 feet of cable
for connection to customer +12 VDC power source.The
MCA series of multicouplers are designed to be used in mobile applications as well
(surveillance vans, aircraft and shipboard SIGINT/COMINT platforms). If +12 VDC power is
available, the multicouplers may be used with the supplied DC plug.For other special DC
power requirements, please give us a call.
