Compatible with any Icom radio that is AH-4 or AH-3 compatible.Controlled from Icom Tuner button on radio or Push button on Tuner.2000 memories for instantaneous band changing.Our focus is on anticipating and meeting our customer’s needs, and providing them with world-class support. LDG Electronics is a family-owned and operated company dedicated to bringing innovative, quality products to the amateur market. ![]() LDG continues to set new standards for autotuners and accessories in amateur radio service. The Z-100A tuner goes anywhere with and HF radio… desktop, portable, parks, islands, or tall summits. Easy integration means plug and play operation installation could not be simpler. * Adjustable amp bypass SWR from 1.5 to 3.The Z-100A features LDG’s famous 10:1 SWR tuning range that matches Dipoles, Verticals, End fed wires, G5RVs or even an Off center fed Windham. * Adjustable SWR threshold from 0.5 to 1.5 * 1.3 to 30 MHz continuous frequency coverage * Direct readout of matching L-C values available after tuning * Highly efficient switched, network matching circuit * Tune in less than 20 seconds, usually less than 5 seconds * Automatically match antennas from 12 to 1,600 ohms impedance (SWR up to 32:1) 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. ![]() MFJ 998 Legal Limit IntelliTuner™ Automatic Antenna Tuners
