WebMay 3, 2024 · In this way we determined that the fris = 45.6 KHz, from which we derive the value of the antenna capacitance, which is 445 pF. Tuning From the examination of the VLF signals received in our area we have seen that the 26.7 KHz signal of the BAFA (NATO) transmitter located in Turkey is well received, at a distance of about 1500 km. WebIf you expect your "good RF ground" to eliminate the second harmonic of a 10-meter signal (56 MHz), you need a wire much shorter than 8 feet long. (No, four feet is not much shorter, and would not work. In fact, a 4-foot "grounding wire" hooked up to the Earth might be a good radiator at 56 MHz.
