Coax In-Line Calibrated RF Ammeter
Connect the MFJ-834 Coax In-Line RF Ammeter between your antenna and tuner/ transmitter/amplifier and measure antenna feedline current in 3 calibrated ranges.
Use it . . . for tuning your antenna tuner/ transmitter/amplifier for maximum radiated power â€¦ for determining antenna feedpoint impedanceâ€¦ for comparing antennas and tuners â€¦ for trouble shooting . . . and for checking for changes.
Tuning for maximum feedline current for any given antenna always gives maximum radiated power!
