MFJ-16010 1.8 – 30 MHz Wire Antenna Tuner


Introducing the MFJ-16010 1.8 – 30 MHz Wire Antenna Tuner, the perfect solution for matching the low output impedance of your transmitter to the high impedance of a random wire antenna. With its variable L-network design, this tuner is capable of effortlessly matching almost any random length of wire to any transmitter from 160 through 10 meters.


With a maximum RF power output of 200 watts, the MFJ-16010 ensures optimal performance when paired with a properly positioned random wire antenna. For best results, it is recommended to have a long, high, and unobstructed random wire antenna. It’s important to note that grounding the random wire antenna should be avoided for optimal performance.

The connectors on the MFJ-16010 are conveniently labelled to facilitate the easy matching of a transmitter to a higher impedance. This is the standard connection method. In instances where you need to match impedances lower than your transmitter’s impedance, such as with a mobile whip antenna, simply interchange the normal transmitter and antenna connections on the MFJ-16010.

While coaxial connectors are used for both antenna and transmitter connections, it’s important to highlight that the MFJ-16010 is specifically designed to match a single random wire and not a coaxial line. However, these coaxial connectors make it convenient to switch between antenna and transmitter connections. MFJ-16010 1.8 - 30 MHz Wire Antenna Tuner

For those opting to connect a single random wire using a standard banana plug, it will fit perfectly into the centre of the SO-239 coaxial connector. To ensure a seamless connection between your transmitter and the MFJ-16010, use a standard coaxial cable with an impedance that matches your transmitter’s output impedance. Additionally, make sure to establish a good ground connection between the MFJ-16010 and your transmitter.
