| Description
The MCA208M
is a specially designed multicoupler for use in the VHF/UHF service band for
radio monitoring and signal surveillance.
Its high performance and rugged design will meet the most stringent
commercial and government requirements.
MCA208M
can support up to eight (8) devices such as radios or spectrum analyzers.
The eight outputs has a gain of +4 dB with a nominal impedance of 50 Ohm.
Input circuitry features a 5-section high-pass filter to shape the frequency
response of the unit and to provide for out-of-band signal rejection.
The MCA208M
is constructed in a rugged die cast aluminum enclosure with mounting
flanges. Light gray baked enamel coating is standard with satin black (Mil)
and olive drab (green/Mil) available on QTY 5 and up.
DC power required is +12 Volts
(nominal) at 100 mA.
A wall adapter (110 VAC/+12 VDC-300 mA) is supplied for the North American
market.
Optional EMI/RFI filtered DC feed thru for hard wiring is also available.
