A common design for a counterpoise is a series of radial wires suspended a few feet above the ground, extending from the base of the antenna in all directions in a "star" pattern, connected at the center. [2] The counterpoise functions as one plate of a large capacitor, with the conductive layers in the earth as the other plate. [2]
Contrapposto (Italian pronunciation: [kontrapĖposto]) is an Italian term that means "counterpoise". It is used in the visual arts to describe a human figure standing with most of its weight on one foot, so that its shoulders and arms twist off-axis from the hips and legs in the axial plane.
In a few cases where rocky or sandy soil has too high a resistance for a buried ground, a counterpoise is used. [11] This is a radial network of wires similar to that in a buried ground system, but lying on the surface or suspended a few feet above the ground.
Counterpoise (1997-2011) is an alternative review journal formerly based in Gainesville, Florida (United States). It was founded in 1997 by Charles Willett (1932-2012), as a project of the AIP Task Force [ 1 ] of the American Library Association 's Social Responsibilities Round Table. [ 2 ]
The later, and often larger and more powerful, counterweight trebuchet, also known as the counterpoise trebuchet, uses a counterweight to swing the arm. It appeared in both Christian and Muslim lands around the Mediterranean in the 12th century, and was carried back to China by the Mongols in the 13th century.
Usually a ground plane or counterpoise is connected underneath the antenna. Other information transmitted by an NDB. The sound of non directional beacon WG, ...
A monopole antenna is a half-dipole ; it consists of a single conductor such as a metal rod, usually mounted over electrically conductive ground, or an artificial conducting surface (called a ground plane, ground system, or a counterpoise).
