MFJ Legal Limit IntelliTuner™ Automatic Antenna Tuner

MFJ 1500 Watt Legal Limit IntelliTuner - MFJ-998

MFJ 1500 Watt Legal Limit IntelliTuner

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.

Review by Jimmy March 25, 2019 3/25/19

The tuner worked pretty much flawless for a year. But then there was a problem where nothing would tune and when I attempted to tune on 40 meters it would try for maybe 15 seconds then quit. I smelled burning wires in the tuner and where my dipole connected to the coax the connector was burnt and shorted. I can't say for sure that it was the tuner. For all I know maybe I was hit by lighting but then again nothing else was damaged. Fortunatly for me when I called it was the very last day of the warranty. So I sent it in and 5 weeks later I got it back. The tuner tunes at low power as it should but sometimes after tuning when I go to talk nothing happens so I have to turn it off then on and it works. Maybe I just got a bad one. When it works its great and for the most part it works but like I said somethimes I have to turn it off then on. you get what you pay for. I wouldn't recommend this product because of the problems I'm having. I will probably spend a little more money and get a better tuner.
