MFJ MFJ-939I: Antenna Tuner, Intellituner, Plug & Play, Automatic, 200 watts, 1.8-30 MHz, for Icom, Each - MFJ 939 Series Automatic Antenna Tuners have been designed for today's home and portable Amateur Radio 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* Requires 13.8 V DC (11.5-15 V) at 750 mAThese MFJ 939 Series tuners include transceiver interface cables for many radio models:* MFJ-939A All Alinco EDX-2 compatible transceivers.* MFJ-939I Icom: Please see the list under "Notes"* MFJ-939K Kenwood: Please see the list under "Notes"* MFJ-939Y Yaesu: Please see the list under "Notes"* MFJ-939Y3 Yaesu FT-1000MP and FTdx-9000* MFJ-939Y4 Yaesu FT-2000 (TX REQ input), and FT-5000Your transceiver wants to "see" a low SWR for best operation and highest power output.
