    MFJ 939 Series Automatic Antenna Tuners have been designed for today's home, portable, or mobile stations. With their small size, MFJ 939 Series compact auto-tuners complement many of today's compact HF transceivers. They may also be used as stand-alone automatic antenna tuners for any transceiver that has an output power of 2-200 watts SSB/CW from 1.8-30 MHz.

    These tuners accept an antenna impedance of 6-1,600 ohms. MFJ 939 Series tuners give you fast, automatic tuning of unbalanced, coaxial-fed antennas. Use an optional 1:1or 4:1 external balun for balanced feed-lines.

    Features include:

    * Automatically matches antennas from 6 to 1,600 ohms impedance (SWR up to 32:1)
    * Handles 200 watts SSB/CW
    * Tunes in less than 15 seconds, usually less than 5 seconds
    * Eight memory banks with over 2,500 memories per bank
    * Over 20,000 non-volatile memories for tuner settings
    * Highly efficient switching L-network matching circuit
    * 1.8 to 30 MHz continuous frequency coverage
    * Audio SWR warnings
    * Built-in radio interface circuitry for compatible transceivers
    * Green "Good SWR" LED
    * SO-239 coax-fed antenna connector
