With its extra wide matching range, the MFJ-904 allows you to tune nearly any antenna, making it versatile and adaptable to different setups. It’s not just a toy – it’s built with real air variable capacitors (600 Volt, 322 pF) and three stacked powder iron toroids to handle real power, not just QRP.

Equipped with a tuner bypass switch, you can easily bypass the tuner when it’s not needed, giving you the flexibility to use nearly any transceiver at full power with either coax-fed or random wire antennas. This means you can operate anywhere and anytime, with a quick and easy setup. Tune out SWR on your mobile whip from inside your car, operate in your apartment with a wall-to-wall antenna, or even set it up in a remote location with a wire dropped from a window or over a tree limb.

Perfect for DXpeditions, field days, and emergency situations, the MFJ-904 is incredibly handy and reliable. Despite its powerful performance, this tuner is remarkably small and lightweight, making it easy to pack away in your briefcase, suitcase, backpack, glove compartment, or desk drawer. In fact, it’s even tiny enough to slide into your back hip pocket!

To further enhance your operating experience, the MFJ-904 includes a Cross-Needle SWR/Wattmeter. This convenient meter allows you to monitor SWR, forward power and reflected power all at a glance. With the push of a button, you can easily select between different power ranges for precise metering.
