The MFJ-998 Full Legal Limit 1500 Watt Intellituner 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 IntelliTune, AdaptiveSearch and InstantRecall algorithms with
over 20,000 VirtualAntenna Memories. When you key your transmitter,
MFJ's InstantRecall checks to see if that frequency has been used
before. If so, tuning is instantaneous. If not, MFJ's IntelliTune
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 Search 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 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 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 preset
amplifier SWR trip-point, the amplifier stays bypassed to provide
automatic SWR protection for your amplifier -- another MFJ exclusive!
Analog SWR/Wattmeter
A large analog Cross-Needle SWR/Watt-meter 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 auto-ranging
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 VirtualAntenna Memory
MFJ new VirtualAntenna 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.
