1500 Watt Antenna Tuner w/ Dummy Load
You get better efficiency, lower losses and a new true peak reading SWR/Watt-meter. It easily handles full 1500 Watts SSB/CW and covers 1.8 to 30 MHz, including MARS and WARC bands into balanced or unbalanced loads.
You can match dipoles, verticals, inverted vees, random wires, beams, balanced lines, coax, mobile whips, shortwave -- nearly any antenna.
New huge 500 pF air variable capacitors give you twice the capacitance for much more efficient operation on 160 and 80 Meters.
Specially shaped plates give low mini- mum capacitance resulting in an extremely wide matching range -- 160 thru 10 Meters.
AirCor™ Roller Inductor gives you lower losses, higher Q and handles more power with no self-resonances.
New fast-tune crank knob lets you reset your roller inductor quickly, smoothly and accurately. A precision gear driven 3-digit turns counter lets you accurately reset your roller inductor for quick band changing.
New TrueActive™ peak reading SWR/ Wattmeter lets you read true peak or average power on all modes. Large, easy-to-read illuminated Cross-Needle meter lets you read SWR and forward/reflected (3000/ 300 Watt ranges) power at a single glance.
Uses 9-Volt battery and/or 12 VDC or 110 VAC with MFJ-1312D.
New high voltage current balun lets you tune high and low impedance balanced lines without core saturation or voltage breakdown.
It’s constructed with two giant 2½ inch toroid cores and wound with high voltage wire connected to high-voltage glazed ceramic feedthrough insulators.
MFJ-989D’s super heavy duty antenna switch is made of two individual ceramic wafers wired in parallel. Extra wide spaced, heavy duty contacts handle extreme voltages and currents.
You can select two coax antennas (directly or through tuner), balanced line/ random wire, or built-in dummy load.
A full-size 300 Watt non-inductive 50 Ohm dummy load is built-in.
New roomy cabinet helps maintain components’ high Q. Vent holes keeps components cool. Super construction -- non-stripping PEM nuts, wing-nut ground post, fire-retardant epoxy glass PC board, and heavy gauge wire throughout. Measures 12 7/8 W x 6 H x 11 5/8 D inches.
