MFJ-974B Balanced Line Antenna Tuner for sale

MFJ-974B Balanced Line Antenna Tuner.


The MFJ-974B is a fully balanced, accurate, balanced line antenna tuner. It offers excellent current balance across a broad matching and frequency range. This tuner utilizes a fully balanced wide-range T-Network with four gear-driven 1000-Volt air variable capacitors, a high-Q air wound tapped inductor for 80-10 Metres, and a separate inductor for 6 Metres. The tuning components are symmetrically mounted to ensure electrical balance. A 1:1 current balun is placed on the low impedance 50 input side to convert the balanced T-Network to an unbalanced operation. This balun is constructed with 50 ferrite beads on RG-303 Teflon coax, providing exceptional and efficient isolation. Additionally, the balun remains cool even at maximum power.
