I didn't think I would care for a SWR/Wattmeter that is so large, until I used it without reading glasses! This meter is, in my opinion, outstanding! Here is a little bit about the meter.... MFJ touts the MFJ-868B Giant SWR/Wattmeter as the World’s Largest HF SWR/Wattmeter. The MFJ-868B measures peak, average forward and reflected power and SWR It operates on 1.8-60 MHz. The MFJ-868B has three power scales, 20, 200 or 2000 watts. The MFJ-868B also has an easy to read 6.5-inch Single- Needle lighted meter.
