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 MFJs exclusive IntelliTuneTM, AdaptiveSearchTM and
InstantRecallTM algorithms with over 20,000 VirtualAntennaTM Memories. When you key
your transmitter, MFJs InstantRecallTM checks to see if that frequency has been used
before. If so, tuning is instantaneous. If not, MFJs IntelliTuneTM algorithm (based on
MFJs 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
tuners measurement range, MFJs 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.
