Minimum SWR does not always mean maximum radiated power -- your tuner or lossy coax may be dissipating power -- and you may not get peak output power even if your tuner or amplifier is properly tuned
Provides direct and clear information on the theory of "antennas from the ground up"
requires guying and radials counterpoises or ground screen
Low SWR lets you rig deliver full power safely
MFJ-854, METER, RF CURRENT METER, 1-30MHz Cushcraft_Antenna Minimum SWR does not alwaysThe MFJ 854 RF Current Meter reads true RF current! It can accurately measure actual RF currents flowing in antenna elements, radials, ground wires and on the outside of coax feedlines. Study and optimize your antenna for peak performance. Its also great for tracking down RFI causing currents on household wiring and cables. MFJ 854s sense coil simply snaps over wires and cables for fast measurements on its easy to red meter.
