Werner Co. was founded in 1922 by Richard D. Werner as "R. D. Werner Co., Inc.," which specialized in metal moldings. R. D. Werner Co., Inc. became a leader in plastics extrusion during the World War II restrictions on civilian metal usage. After the war, Werner started working with aluminum and developed an emphasis on producing aluminum ...
A fan-beam antenna is a directional antenna producing a main beam having a narrow beamwidth in one dimension and a wider beamwidth in the other dimension. This pattern will be achieved by a truncated paraboloid reflector or a circular paraboloid reflector. Since the reflector is narrow in the vertical plane and wide in the horizontal, it ...
A lens antenna is made from a layer of dielectric, or a metal screen, or multiple waveguide structure of varying thickness, mounted in front of a feed antenna. The waveguide / screen / dialectric refracts the radio waves, focusing them on the feed antenna, similar to a focusing lens placed in front of a flashlight. Dielectric resonator
This means that if there is a 4" (100 mm) gutter projecting from the side of a building, a fixed ladder would have to have standoff brackets that were at least 11" (7" + 4") (280 mm) in length. Cages: Cages are optional for fixed ladders with a floor to floor elevation of less than 20' (6100 mm). They are often available for ladders with ...
The antenna used for broadcasting through the 1920s was the T-antenna, which consisted of two masts with loading wires on top, strung between them, requiring twice the construction costs and land area of a single mast. [2] (pp 77–78) In 1924 Stuart Ballantine published two historic papers which led to the development of the single mast antenna.
An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. [ 1 ] : p.149 [ 2 ] The individual antennas (called elements ) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase ...
The folded unipole antenna is a type of monopole mast radiator antenna used as a transmitting antenna mainly in the medium wave band for AM radio broadcasting stations. It consists of a vertical metal rod or mast mounted over and connected at its base to a grounding system consisting of buried wires. The mast is surrounded by a "skirt" of ...
It consists of a ring-shaped toroidal iron core with the primary winding wrapped around it, mounted on a bracket extending from the concrete base below the antenna insulator, connected to the lighting power source. The secondary winding which provides power to the mast lights is a ring-shaped coil that threads through the toroidal core like two ...
