Web13 jun. 2024 · At 30 MHz a wavelength is 10 meters or 33 feet. Thus 4 times 33 equals 132 feet. So my 150 ft is off by 12%. Not bad for a quick guess. Again, the point was to illustrate that if you have a structure with a transmit antenna at 40 ft and a receive antenna at 60 ft, then you might expect 40 to 50 dB isolation.
