Mfj-989C versa tuner v 3 kilowatt roller inductor
This Tuner is in fine working condition. It has minor scratches and slight indent on the top cover. The inductor was replaced with an air coiled inductor that is available from MFJ. This will include the manual and the AC Adapter to light the meter with.
The MFJ-989C roller inductor tuner is a 3000 watt
PEP input, 1500 watt PEP output antenna tuner.
These power ratings are for load impedances of 35-500 ohms. The MFJ-989C is designed to match 50
ohm output amplifiers, transmitters or transceivers to virtually any antenna. Peak and average forward
power, reflected power, and SWR are displayed on the MFJ-989C's illuminated cross-needle meter.
The MFJ-989C uses a roller inductor "T" matching network. It continuously tunes all frequencies from
1.8 through 30 MHz. It will match dipoles, inverted-vee's, verticals, mobile whips, beams, random wires,
and many other antennas. The MFJ-989C has rear panel connectors for coaxial and single or two wire
built-in balun will work with balanced open wire, twinlead, or twin-axial feedlines.
An internal six position antenna-selector switch selects a built-in 50 ohm dummy load, two coaxial line
outputs, or a single wire line-balanced line output. The coaxial line outputs can be selected in tuned
(with tuner's matching network in line) or direct (no matching circuit) configurations.
