The MFJ-9982 ContinuousCarrier™ antenna tuner handles 2500 Watts continuous carrier output on all modes and all HF bands into most unbalanced antennas -- even on 160 Meters where even the best antenna tuners fail!
The MFJ-9982 gives you every feature you'll ever want in a high power tuner -- wide matching range, 1.8 to 30 MHz coverage, 6-position antenna switch, 4-core balun, dummy load, true peak/average lighted SWR/Wattmeter, 6:1 reduction drives with detailed logging scales, 3-digit turns counter, extra large knobs.
New Components, New Technologies
The Heart and Soul of the MFJ-9982 is its roller inductor and variable capacitors.
MFJ's high power, high-Q continuous current AirCore™ roller inductor is no ordinary roller inductor! Its edge wound from thick .06-inch silver-plated solid copper strap.
It can carry huge, circulating RF currents and withstand tremendous heat that'll melt or burn up ordinary roller inductors.
Self-insulating construction reduces stray capacitance -- keeps self-resonant frequencies high and out-of-the-way. Dual, silver-plated compression wheels give ultra low-resistance contacts. New, fast-tune crank knob.
High-current, high-capacitance 1000 pF and 500 pF air variable capacitors have low minimum capacitance and are self-insulating.
These newly developed capacitors and MFJ's patent pending innovation gives you very high efficiency on 160/80 Meters and extremely wide matching range on 10/12/15 Meters at 2500 Watts -- a feat only the MFJ-9982 has achieved.
Hi-Voltage/Current Antenna Switch
The antenna switch is completely isolated to handle high-voltage high impedance antennas. High-current, low impedance antennas are handled by parallel sets of high-current contacts of two ceramic switches.
New, powerful 4-Core Balun with four 2½" cores and 12-gauge Teflon™ wire. Run balanced lines at full 2500 Watts SSB/CW continuous, 24/7.
New Balanced Line Feed-Thru Insulator.
Allows massive antenna currents to flow directly to the antenna capacitor without passing though lossy screws or bolts.
New, TrueActive™ Peak Reading Circuit reads true peak or average power on all modes. Cross-Needle meter simultaneously reads SWR, Forward and Reflected power.
1500 Watt Dummy Load
1500 Watt air-cooled, non-inductive 50 Ohm resistor. 100W/10 min., 1.5kW/10 sec.
New, roomy cabinet maintains high Q. Vent holes. Heavy gauge, .08 inch aluminum, braced chassis, vinyl cover, non-stripping PEM nuts, heavy 10-gauge or copper strap wiring throughout.
13¾"W x 7"D x 15¾"D inches. 15 pounds.
