A radio mast base showing how virtually all lateral support is provided by the guy-wires. The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guy-wires. [1] A mast
Radio masts and towers support antennas (also known as aerials) for telecommunications and broadcasting, including television. Subcategories This category has the following 4 subcategories, out of 4 total.
The four main components of a mast or pole photography system are: (1) the telescoping mast or pole, (2) a high resolution digital camera that is, (3) controlled remotely with a smartphone or computer tablet running a mobile app, and (4) a remote controlled and powered pan/tilt head for pointing the camera.
It is constructed of two telescoping rods attached to a base, which extend out to about 1 m (3.3 feet) length (approximately one-quarter wavelength at 54 MHz) and can be collapsed when not in use. For best reception, the rods should be adjusted to be a little less than 1 / 4 wavelength at the frequency of the television channel being ...
(left) Three large fiberglass whips mounted on a mast. (right) Fiberglass whip for 2 m and 70 cm amateur radio bands. The whip antenna is a monopole antenna , and like a vertical dipole has an omnidirectional radiation pattern , radiating equal radio power in all azimuthal directions (perpendicular to the antenna's axis), with the radiated ...
A modified mast antenna, usually grounded at its base, augmented by one or several parallel wires called "skirt wires" that attach to the mast part-way up the antenna. The skirt wires can attach at any height between part-way up and the top of the mast. One or more of the skirt wires is fed with the signal, similar to a gamma match.
Guyed radio masts are typically tall enough that they require several sets of guy lines, 2 to 4, attached at different heights on the mast, to prevent them from buckling. An exception to multiple guys was the Blaw-Knox tower , widely used during the 1930s, whose distinctive wide diamond ( rhomboidal ) shape gave it the shear strength that it ...
Telescoping in mechanics describes the movement of one part sliding out from another, lengthening an object (such as a telescope or the lift arm of an aerial work platform) from its rest state. [1] In modern equipment this can be achieved by a hydraulics , but pulleys are generally used for simpler designs such as extendable ladders and amateur ...
