This is an automatic antenna tuner that can automatically match the antenna and transmitter, and has multiple modes and functions, such as digital power meter, power bar meter, SWR bar meter, L-network meter, antenna indicators, IntelliTune, memory, power level, LC limit, meter range, auto/semi and StickyTune.
The MFJ-993B IntelliTuner is an automatic antenna tuning center designed to match antennas with impedances ranging from 6 to 1600 ohms (at 300 watts) or 6 to 3200 ohms (at 150 watts). It features a switching L-network, a built-in frequency counter, and a lighted cross-needle SWR/wattmeter. The unit supports two antennas with over 20,000 non-volatile memory locations for storing tuner settings.
| Impedance matching range | 6 to 1600 ohms (300 watts) or 6 to 3200 ohms (150 watts) |
|---|---|
| Frequency range | 1.8 to 30 MHz continuous coverage |
| Capacitance range | 0 to 3908 pF nominal |
