MFJ-815D HF/6M SWR/Wattmeter
The MFJ-815D covers 1.8-60MHz and reads the true-peak or average power on a large illuminated three-inch Cross-Needle Meter. Its TrueActive peak reading circuit gives you an incredibly accurate SWR and power reading in SSB and CWover a wide frequency range. The Cross-Needle Meter reads SWR and true peak average, forward and reflected power simultaneously -- all in a single glance. Has mechanical adjustment for accurately zeroing the meter. Push button selects range, meter lamp on/off and peak for SSB or average for CW operation. SO-239 Connectors. MFJ-815D has 3000 and 300 Watts forward and 600/60 Watts reflected power ranges and reads SWR from 1:1 to 8:1. LED Meter lamp uses 12 VDC or 110 VAC with optional MFJ-1312D. TrueActive Peak Reading Circuit can use 9 Volt battery. All metal black aluminum cabinet measures 6W x 3 1/2H x 4 1/2D inches.
