1.5kW 1.8-30MHz AUTO TUNER with METER/LCD DISPLAY MFJ-998 HF AUTOMATIC Coupler ANTENNA TUNER
The MFJ-998 Full Legal Limit 1500 Watt IntellitunerTM takes you to the final
level in automatic antenna tuners. With a capability of 1500 watts SSB and CW, coupled with automatic tuning, your high-power station can now operate essentially hands-free even when frequency and band changes are made.

Fast Automatic Tuning
The MFJ-998 instantly matches impedances from 12-1600 ohms using MFJ's exclusive IntelliTuneTM, AdaptiveSearchTM and InstantRecallTM algorithms with over 20,000 VirtualAntennaTM Memories. When you key your transmitter, MFJ's
InstantRecallTM checks to see if that frequency has been used before. If so, tuning is instantaneous. If not, MFJ's IntelliTuneTM algorithm (based on MFJ's efficient SWR Analyzer technology) measures the impedance, snaps the necessary
components in place, and then fine-tunes the SWR. If the antenna impedance is outside the tuner's measurement range, MFJ's Adaptive SearchTM algorithm measures the frequency and determines only relevant component values -- which are then
searched for fast tuning.

Safe Automatic Tuning and Amplifier Protection
The MFJ-998 includes MFJ's Amplifier Bypass ControlTM -- an MFJ exclusive feature! When used with a transceiver interface cable, tuning is safe and "stupid-proof"! When a tuning cycle is initiated, the MFJ- 998 first bypasses any in-line
amplifier. Next, the MFJ-998 initiates a low-power CW tuning carrier from your transceiver. When tuning is complete, the MFJ-998 reverts your transceiver to its prior power and mode, and re-enables the amplifier. This entire cycle typically
takes less than a second! Finally, if the MFJ-998 cannot find a match better than a pre-set amplifier SWR trippoint, the amplifier stays bypassed to provide automatic SWR protection for your amplifier -- another MFJ exclusive!

Analog SWR/Wattmeter
A large analog Cross-Needle SWR/Wattmeter displays selectable 300/60 watt or 3000/600 watt forward/reflected full-scale ranges. You can even select automatic power ranging -- the best power range is automatically selected for you.

Digital LCD SWR/Wattmeter
A two-line, 16-character backlit LCD meter displays SWR, forward/reflected power, frequency, antenna selected, an autoranging bargraph power indication, and much more. You can even read the final matching inductor and capacitor values
should you want to build your own fixed matching network. Simple menus determine displayed information - no complex button combinations to remember!

MFJ VirtualAntennaTM Memory
MFJ new VirtualAntennaTM Memory system gives you 4 antenna memory banks for each of 2 switchable antenna connectors. Select up to 4 antennas on each antenna connector. Each antenna has 2500 memories, 20,000 total. Has two coax connectors
and a binding post for end-fed long wire antennas.

Download and Upgrade Remotely
Field upgradeable firmware via the serial port -- download and upgrade your MFJ-998 as new features are introduced!

Plus Much More!
Built-in radio interface provides control of most amateur transceivers. Automatic bypassing when excessive tuning power or power in excess of 1500 watts is applied. Use balanced line antennas with external MFJ-912, $59.95, 1.5 kW 4:1
balun. MFJ-998 is the smallest full legal-limit auto-tuner in the world! 13Wx4Hx15D inches fits easily into your ham station. Weighs just 9 pounds -- great portability! Requires 10-15VDC at 1.3 amps maximum. For more information on optional
