Each of the two antenna selections has four banks of memory, which can learn and remember more than 2,500 frequencies and tuner settings per bank. The next time you operate on that frequency (or close to it) and antenna, these tuner settings are instantly restored and you're ready to operate in milliseconds. When you transmit, they automatically adjust for minimum SWR and remember the frequency and tuner settings, which are safely stored in non-volatile memory. All MFJ 998 IntelliTuners™ learn and remember. And once a match is found, the matching network values can be displayed, so you may design your own fixed matching network if desired. The nominal tuning ranges are 0 to 24 microhenry and 0 to 3,900 pF (input) or 0 to 970 pF (output). This provides a total of 81,664 L/C tuning combinations. A maximum of 256 values of inductance and 256 values of input capacitance, or 64 values of output capacitance, is available. They're rated at 1,500 watts SSB/CW and will match impedances from 12 to 1,600 ohm antennas (SWR up to 32:1). MFJ 998 legal limit tuners include a highly efficient switching L-network with wide matching capabilities, 1.8 to 30 MHz coverage, cross-needle power meters, a backlit LCD display, a radio interface port, and heavy-duty 16 amp/1,000 V relays. Each of the two antenna outputs has four banks of memory, and each memory bank has over 2,500 non-volatile memories for tuner settings. MFJ's exclusive InstantRecall™, IntelliTune™, and AdaptiveSearch™ algorithms give you fast, automatic tuning with more than 20,000 non-volatile VirtualAntenna™ memories. These exclusive MFJ antenna tuners fully protect your amplifier during tuning and will even take your amplifier off-line should the SWR increase above a user-defined preset limit. MFJ 998 tuners include MFJ's Amplifier Bypass Control™. Balanced feedlines may be used with an external 4:1 balun connected to the MFJ 998 antenna output. MFJ 998 tuners let you rapidly tune almost any unbalanced or single-wire antenna automatically. MFJ 998 legal limit IntelliTuner™ automatic antenna tuners are comprehensive, automatic antenna tuning centers with an SWR/wattmeter and an antenna switch for two antennas. 500 Watt Power Combos are available, too.MFJ 998 Legal Limit IntelliTuner™ Automatic Antenna Tuners Take a moment to explore Elecraft’s line of Automatic Antenna Tuners here. This provides the amateur radio operator with just the kind of experience and allows them to learn and understand more about how their radio equipment can further their experiences in the hobby. Further, they are all rated to tune antennas and transmission lines up to a 10:1 SWR at rated power.Ĭonsistent with the ham radio hobby, our T1 and KAT500 tuners are available as Modular Kits or Factory Built. Fully trainable, these automatic tuners memorize the tuning elements needed for fast QSY between bands. Shipping Box Sets (Item return for Servicing)Įlecraft produces a wide range of automatic antenna tuners from 20 Watts and up to 500 watts.Īll of our tuners are optimized to operate with Elecraft transceivers, and the T1 and KAT500 can be used with most non-Elecraft transceiver available today.Īll Elecraft linear amplifiers use fast, silent T/R switching diodes for fast operation, are fully fault protected and all solid state for no-tune, fast QSY between bands.Accessories (Speaker, Mics, Power Supply, Compact Cases, K-Pod).
