MFJ-976 Balanced Line Tuner


Introducing the MFJ-976 Balanced Line Tuner – the ultimate solution for achieving optimal antenna performance. Designed to handle a full 1500W SSB and CW, this fully balanced antenna tuner brings exceptional balance and wide matching ranges to your radio setup.


With its continuous coverage from 1.8 to 30 MHz, including all WARC bands, the MFJ-976 offers versatility and compatibility across a broad range of frequencies. It effortlessly tunes any balanced lines, whether it’s the 600 Ohm open wire line, 450/300 Ohm ladder lines, or the 300/72 Ohm twin lead — shielded or unshielded. This tuner even caters to random wires and coax-fed antennas, making it a one-stop solution for all your tuning needs.

Experience the ease and efficiency of the MFJ-976’s fully balanced extremely wide-range T-network, which simplifies tuning with just three knobs. No more complicated switching between high and low impedance or adding additional capacitance of L-networks. The four separate 500 pF capacitors, arranged in two gangs, provide a total of 2000 pF for highly efficient low-loss separation on 160 meters.MFJ-976 Balanced Line Tuner

The MFJ-976 doesn’t compromise on performance. Its low minimum capacitance ensures excellent 10-meter performance, while the exclusive Self-Resonance KillerTM high-Q AirCoreTM roller inductor with silver-plated contacts guarantees top-notch reliability and longevity.

Featuring a heavy-duty 1:1 current balun, the MFJ-976 maintains superb balance and remains cool even at maximum power. The true active peak reading lighted Cross-Needle SWR/Wattmeter allows you to effortlessly monitor SWR, true peak, or average forward and reflected power on the 300/3000-watt ranges, providing real-time information at a glance.
