Web8 dec. 2024 · The Beverage antenna relies on "wave tilt" for its operation. At low HF frequencies, a vertically polarized radio frequency electromagnetic wave traveling close to the surface of the earth with finite ground conductivity sustains a loss that causes the wavefront to "tilt over" at an angle. The electric field is not perpendicular to the ground … Web8 dec. 2024 · Mr Beverage was working on the antenna 100 years ago, though the patents came through in 1921.

He discovered in 1920 that an otherwise nearly bidirectional long-wire antenna becomes unidirectional by placing it close to the lossy earth and by terminating one end of the wire with a resistor. In 1921, Beverage was granted a patent for his antenna. That year, Beverage long-wave receiving antennas up to 14 km (9 miles) long had been installed at RCA'… Web13 apr. 2024 · You’ll need a good antenna to do that, which is where this homebrew loop antenna for the shortwave radio bands shines.
