MCA108M HF Receiver Multicoupler
500 kHz to 50 MHz
8 Ports

Description

The MCA108M 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.

MCA108M 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 50 MHz low-pass filter to shape the frequency response of the unit  and to provide for out-of-band signal rejection.

The MCA108  is constructed in a rugged die cast aluminum enclosure with mounting flanges. Black powder coating is standard with Light Gray (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.
