MFJ 1500 Watts Legal IntelliTuner Limit

Full 1500 watt SSB/CW...Digital and Analog SWR/Wattmeter. . .
All the features of MFJ IntelliTuners-- ultra-fast, secure automatic tuning. . . Wide Tuning Range (12-1600 Ohm from 1.8 to 30 MHz). . . Radio Interfaces. . . Built-in switch Antenna for two coaxial / long wire. . . Automatic bypass protects your amplifier. . . Software field updatable. . . Very compact!

The MFJ-998 full legal limit 1500 Watt Intellituner takes you to the ultimate level of automatic antenna tuners. With 1500 watt SSB and CW capabilities, coupled with automatic tuning, the high-powered station can now operate essentially hands-free, even with frequency and band changes.

Fast automatic tuning

The MFJ-998 instantly matches impedances from 12-1600 Ohms using MFJ`s exclusive IntelliTune, AdaptiveSearch and InstantRecall algorithms with over 20,000 VirtualAntenna memories. When you key in the transmitter, MFJ`s InstantRecall checks if that frequency has been used before. If so, attunement is instantaneous. Otherwise, MFJ`s IntelliTune algorithm (based on MFJ`s Efficient SWR Analyzer technology) measures the impedance, snaps the necessary components into place, and then fine-tunes the SWR. If the antenna impedance is outside the tuner`s measurement range, MFJ`s Adaptive search algorithm measures the frequency and determines only the values of the relevant components - which are then searched for fast tuning.

Safe automatic tuning and amplifier protection

The MFJ-998 includes the MFJ's Amplifier Bypass Control - an MFJ exclusive feature! When used with a transceiver interface cable, tuning is safe and "stupidproof"! When a tuning cycle is initiated, the MFJ-998 first bypasses any in-line amplifier. Next, the MFJ-998 initiates a low-power CW vector tuning from the transceiver. Once tuning is complete, the MFJ-998 returns the transceiver to its previous power and mode and re-enables the amplifier. This entire cycle typically takes less than a second! Finally, if the MFJ-998 fails to find a better match than a preset trip-point SWR amplifier, the amplifier remains bypassed to provide automatic SWR protection for the amplifier - another MFJ exclusive!

Analog SWR / Wattmeter

A large analog cross-needle SWR/Watt meter display with selectable 300/60 watts or 3000/600 watts forward/reflected full-scale ranges. You can also select automatic power ranging - the best power range is automatically selected for you.

SWR Digital LCD / Wattmeter

A two-line, 16-character backlit LCD meter displays SWR, forward/reflected power, frequency, selected antenna, auto-ranging histogram, power indication
and more. You can also read the final matching inductor and capacitor values should you want to build your own fixed matching network. Simple menus
determine the information displayed - no complex key combinations to remember!

MFJ VirtualAntenna Memory

New VirtualAntenna Memory System MFJ offers 4 banks of antenna memory
each with 2 switchable antenna connectors. Select up to 4 antennas on each antenna connector. Each antenna has 2500 memories, 20,000 in total. It has two coaxial connectors and a long end-fed wire antenna clamp.
