WebA classic Beverage receiving antenna requires a lot of space. It is a long wire, one or more wavelengths long, mounted near to the ground and oriented in the direction of the desired reception. A nominal 9:1 balun is required at the juncture of the wire and 50- or 75-Ohm coaxial feedline.The far end is terminated with a nominal 600-ohm resistance. http://www.pg1n.nl/articles.php?lng=en&pg=367

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 … Web15 jul. 2024 · The antenna was built on the ground. The halyard/pulley system would later hoist the antenna into position. Using the general formula 468/f (MHz)=L (ft), I cut the antenna to a length of 47 feet (14.32 meters).
