Inserted directly into the antenna feedline, measures antenna current in three calibrated ranges.


Use the RF current meters for precise measurements of antenna currents, while tuning your amplifier or tuner, calculate the impedance of your antenna feedpoint. Highly suitable for experiments with antennas or monitor changes of the antenna during operation.


Tuning for maximum antenna current usually results in highest radiated power (power rises to the square of the current). The minimum SWR is not necessarily the point where the highest antenna current is found. Or compare the efficiency of various tuners, the MFJ HF current meters identify losses quite easily.


The MFJ HF current meters are solid constructed devices for shortwave. Frequency range 1 to 30MHz, calibrated ranges for max. 0,3, 1 or 3A. 3A correspnd to 450W on a 50Ω antenna.


Connectors PL sockets for direct insertion into the feedline. Large, backlit analog instrument, size 152 x 89 x 114mm, weight 425g.
