Hi Kevin, I and some of friends of mine have used AA-54 for 136kHz. It's easy to measure resonant frequency, impedance and resistance with combination of an antena coil, antenna capacitance and earth
Hello LF gang, Has any one tried a RigExpert AA-30 or AA-54 antenna analyser ? They should appeal to the LF enthusiast as they go down to 100 kHz, 73, Kevin ZL4MD
