MFJ-1020C SWL Indoor Active Antenna
New technology uses a dual gate MOSFET and a gigahertz bandwidth buffer. It improves gain and selectivity, reduces noise and intermod, and is NOT prone to self-oscillations that can severely damage your receiver.
With the MFJ-1020C tuned indoor active antenna youll rival reception of outside wire antennas hundreds of feet long and pick up signals loud and clear from all over the world.
MFJs unique tuned circuitry minimizes intermod, improves selectivity and reduces noise outside the tuned band. You can also use it as a tuned preselector with an external antenna.
The MFJ-1020C covers 0.3 to 40 MHz including VLF, AM broadcast, all shortwave and all amateur radio bands. It has Tune, Bane, Gain, On-Off/Bypass controls and SO-239 coax connectors. It uses a 9 volt battery, 9-18 VDC or 10 VAC with the optional MFJ-1312D power supply. The MFJ-1020C measures 6W x 2H x 5D inches. It includes a telescoping whip.
