The MFJ-974HB is a fully balanced true balanced line antenna tuner.


It gives you superb current balance throughout its very wide matching and frequency range.  


The MFJ-974HB gives you excellent current balance, very wide matching range (12-2000 Ohms) and covers 10-160M continuously including all WARC bands. Handles 300 Watts SSB PEP and 150 Watts CW.


Tuning is fast and easy - - just three tuning controls. You can even adjust for highly efficient broadband low-Q operation or use higher Q when you encounter extreme loads.


The MFJ-974HB tunes any balanced lines including 600 Ohm open wire line, 450/300 Ohm ladder lines, 300/72 Ohm twin lead - - shielded or unshielded.


Superb current balance minimizes feedline radiation that can cause troublesome TVI and RFI, painful RF bites, mysterious RF feedback problems and radiation pattern distortion.


The MFJ-974HB is a fully balanced wide range T-Network using four gear driven 1000-Volt air variable capacitors and high-Q air wound tapped inductor for 80-10 Meters and separate inductors for 6 and 160 Meters. The tuning components are mounted symmetrically to insure electrical balance. A 1:1 current balun is placed on the low impedance 50 input side to convert the balanced T-Network to unbalanced operation.
