What is t-aerial?
and T-Aerial is a type of antenna that transmits and receives television and radio signals. It gets the name of its design, which consists of a horizontal wire suspended a certain distance above the ground with a towing wire leading down and forming the shape of "T." The ability of T-aerial transmission or receiving signals is influenced by a number of factors, including the resistance of the wires, their length and the ratio of these lengths. The wavelength of the signal to be transmitted or accepted. T-aerial can be a simple design with one horizontal and one vertical wire or may include other wires at the top. It may also have a radial pattern of buried wires at the bottom of the vertical wire. The vertical wire is connected to its base to the transmitter or receiver. The horizontal conductor is connected to the vertical wire and suspended above -ground, usually supported at each end of the poles or towers, structures called masts. The horizontal conductor must be well insulated from the support towers. The thickness or width of wires and their length is affected by frequencies to betransmitted or accepted.
Transfer of medium and long wavelength signals is the primary use of T-Aerial antennas. The simple vertical antenna is ideal for the transmission and receiving of these wavelengths, but in situations where a very high vertical antenna is not practical, T-Aerial is often a good alternative. Engineers and electronics enthusiasts have a number of formulas to calculate ideal wire dimensions. In general, more than one configuration is possible for maximum efficiency and dimensions that are the easiest for construction are usually selected.
Any given T-Aerial could provide the same performance with northern other possible two-wire configurations. One example of popular T-Aerial design is built vertical 11 m (36 ft) and horizontal 50 m (164 ft). The same performance can also be achieved using T-A News in which the horizontal and vertical wires are almost the same length-vertical meter23 m (75 ft) and horizontal measurements 23.5 m (77 ft).
Further modifications of the basic T-Aerial design include other wires at the top of the antenna that are connected and run parallel to the horizontal wire. This arrangement is commonly called a cage. A number of wires can be attached to the bottom of the vertical wire. These wires are called radials because they stretch from their connection with the vertical wire in a radial pattern, such as the wheels. Radial wires are usually buried in the ground.
