MFJ-834, RF IN-LINE CURRENT METER, COAX, 1-30MHz, 3AMP

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, for determining antenna feedpoint impedance, for comparing antennas and tuners, for trouble shooting and for checking for changes. Tuning for maximum feedline current for any given antenna always gives maximum radiated power! Any adjustment - transceiver or amplifier tuning/loading controls, antenna tuner settings, whatever - that increases feedline current improves power transfer and gives you a stronger radiated signal. Radiated power increases rapidly because power increases as the square of the current. 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. Use the MFJ-834 to determine best anten
