AN-48x also works with portable radios that do not have an external antenna jack.
Designed to enhance radio receptions in all AM (Amplitude Modulation) bands including shortwave, mediumwave and longwave
Wide frequency coverage, AM: 520-1700 KHz, SW: 3.50-20.00 MHz, LW: 120-400 KHz
Powered amplication, 2 AAA batteries are required (NOT included)
Includes various connection cables and accessories, compatible with virtually all types of radios

Product: MFJ Indoor Active Antenna, HF and Ham Guides TM Pocket Reference Card Bundle
Brand: MFJ
Description: HF Active Indoor Antenna
MFJ invented the tunable active antenna! Numerous copies have been made without success -- including most recent ones. Why? Because MFJ has made continuous improvements where others have not. The MFJ-1020C has been completely redesigned with new technology.
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 you'll rival reception of outside wire antennas hundreds of feet long and pick up signals loud and clear from all over the world.
World Radio TV Handbook says the MFJ-1020 is a "fine value . . fair price . . best offering to date . . performs very well indeed."
MFJ's 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 MFJ-1312D. The MFJ-1020C measures 6W x 2H x 5D inches. It includes a telescoping whip.
