The Beverage Antenna: A Mile of Wire That Hears Whispers The Beverage is a kilometre of wire that only listens. This guide explains the wave antenna's principle, its termination and its low-band miracles. Quick facts Inventor Harold Beverage Patent era 1921 Length 1-3 wavelengths Termination ~450-600 ohm Direction toward far end Signals arriving along the wire add progressively; noise from everywhere else mostly cancels, and the termination resistor keeps the pattern one-directional. The Beverage does not amplify - it subtracts, until call signs stand alone in the quiet. Start now: https://morsecodeworks.com/ Morse Code Works - free Morse code tools and guides. Reference chart
