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.
