For Sale, MF HF Tuners purchased for evaluation only, never put into service.

All in new condition, most are in the original OEM packaging. The only use has been

to initially evaluate the feasibility of using one of these at my remote site in FN44.

Ultimately, I installed all resonate antennae at the site so a tuner was not required.

MFJ-998

MFJ 998 Legal Limit IntelliTuner™ Automatic Antenna Tuners (MSRP $769.95) New Condition $500/bo

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 tuners let you rapidly tune almost any unbalanced or single-wire antenna automatically. Balanced feedlines may be used with an external 4:1 balun connected to the MFJ 998 antenna output. MFJ 998 tuners include MFJ's Amplifier Bypass Control™. 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's exclusive InstantRecall™, IntelliTune™, and AdaptiveSearch™ algorithms give you fast, automatic tuning with more than 20,000 non-volatile VirtualAntenna™ memories. 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 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. 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). A maximum of 256 values of inductance and 256 values of input capacitance, or 64 values of output capacitance, is available. This provides a total of 81,664 L/C tuning combinations. The nominal tuning ranges are 0 to 24 microhenry and 0 to 3,900 pF (input) or 0 to 970 pF (output). And once a match is found, the matching network values can be displayed, so you may design your own fixed matching network if desired. All MFJ 998 IntelliTuners™ learn and remember. When you transmit, they automatically adjust for minimum SWR and remember the frequency and tuner settings, which are safely stored in non-volatile memory. 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. 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.

Features include:
* Automatically match antennas from 12 to 1,600 ohms impedance (SWR up to 32:1)
* Handle 1,500 watts SSB/CW
* Tune in less than 20 seconds, usually less than 5 seconds

MFJ-994B

MFJ 994B IntelliTuner™ Automatic Antenna Tuners (MSRP $419.95) New Condition $295/bo

MFJ 994B IntelliTuner™ automatic antenna tuners let you rapidly tune any antenna automatically—unbalanced or single-wire (or balanced, with an external balun). They may be operated at a remote distance through a 9-pin to 9-pin computer cable using the MFJ remote control unit. MFJ's exclusive InstantRecall™, IntelliTune™, and AdaptiveSearch™ algorithms give you fast, automatic tuning with more than 20,000 non-volatile VirtualAntenna™ memories. There are four banks of memory, and each memory bank has over 2,500 non-volatile memories for tuner settings. These tuners include a highly efficient switching L-network with wide matching capabilities, 1.8 to 30 MHz coverage, cross-needle power meters, a port for an accessory remote control, a radio interface port, and heavy-duty 16 amp/1,000 V relays. They are rated at 600 watts PEP SSB and 600 watts CW. A maximum of 192 values of inductance and 192 values of capacitance are available. With the inductance switched between the input and output side, this provides a total of 73,728 L/C tuning combinations. The nominal tuning ranges are 0 to 17 microhenry and 0 to 2,950 pF. All MFJ IntelliTuners™ learn and remember. When you transmit, they automatically adjust for minimum SWR and remember the frequency and tuner settings, which are safely stored in non-volatile memory. 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. There are four banks of memory, which can learn and remember more than 2,500 frequencies and tuner settings per bank.
