MCA104 HF Receiver Multicoupler
500 kHz to 50 MHz
4 Ports


The MCA104 is a specially designed multicoupler for use in the HF band,
500 kHz to 50 MHz, for radio monitoring and signal surveillance.
Its high performance and rugged design will meet the most stringent
commercial and government requirements.

MCA104 can support up to four (4) devices such as radios or spectrum
analyzers. The four outputs has a gain of +4 dB with a nominal impedance
of 50 Ohm. The input circuitry features a 5-section 50 MHz low-pass
filter to shape the frequency response of the unit  and to provide for
out-of-band signal rejection.

The MCA104  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 75 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.
