Download the MFJ-267 Manual 1.5 kW Dry Dummy Load has built-in precision, true peak-reading SWR/Wattmeter switchable to external antenna! World's most versatile 1.5 kW dummy load has a built-in true peak reading SWR/Wattmeter that you can switch and use independently! You'll find tons of uses! Tune up your transceiver, linear amplifier, or antenna tuner into a safe 50 Ohm dummy load at full power. Then instantly switch to your antenna and monitor SWR, forward, and reflected power. Use for testing/tuning transmitters, transceivers, amplifiers, antenna tuners, baluns, transformers, filters, matching networks, coax, stubs, transmission lines, and antennas. The 50-Ohm dry dummy load works DC to 60 Mhz. SWR is below 1.3:1 at 30 MHz. Can handle 100 Watts for ten minutes or 1500 Watts for ten seconds. Comes with power derating curve. Extra-large three-inch lighted Cross-Needle Meter reads SWR (1:1 to 8:1), forward, and reflected power simultaneously. Reads true peak PEP or average power on 300/3000 Watts forward and 60/600 Watts reflected power ranges 1.8-54 MHz. High accuracy comes from a carefully designed directional coupler, an accurate active-peak reading circuit and a precision d'Arsonval meter movement. RF tight perforated aluminum cabinet. 4 1/2 W x 3 1/2 H x 10 D inches. Uses 12 VDC or 120 VAC with the MFJ-1312D.
