Mfj-914 auto tuner extender is a useful tool for extending the tuning range of automatic antenna tuners on rigs.


The MFJ-914 Auto Tuner Extender addresses the limitations of automatic ATUs by offering a wide range of impedance matching capabilities. This heavy-duty device is designed to provide the flattest frequency response and lowest loss possible across frequencies ranging from 1.8 to 30MHz. With a maximum power handling capacity of 300W, the MFJ-914 has seven load positions, ground and by-pass options, SO-239 sockets, and a connection for a dummy load.

Measuring 150 x 42 x 90mm and weighing 415g, the MFJ-914 Auto Tuner Extender is a compact yet robust solution for impedance-matching needs. Its carefully engineered design ensures optimal performance across a broad frequency spectrum. Including a separate earth terminal further enhances its versatility, making it a valuable addition to any radio operator's setup.
