Antenna is an electronic device. Basically it is an aerial electronic conductor. Heinrich Hertz discovered an antenna in 1886. The antennas convert the radio frequency electric current into an electromagnetic wave. Antennas are used in radio and television broadcasting. They also have an application in communication systems, radar and space explora...
Dipole antenna is nothing but an antenna with two poles. It is the simplest type of antenna. A dipole antenna is an aerial half a wavelength long. It is an electrical device that is used to send or receive radio or television signals. It consists of two rods connected to a transmission line at the center. It has maximum radiations at right...
Choose the right TV antenna can be a business of the frustration. However, if someone prefers to receive TV through an antenna, rather a subscription of the satellite or of the cable, there are pairs of the equipment that will make life easier. One must choose a roof or a mounted antenna TV attic. This will give the best occasion to choose upon a g...

The HDTV antennas are helpful in providing digital pictures without any disturbance of noise. The HDTV antenna picks up an HD signal. A HDTV antenna is typically a high quality antenna. There...
Antennas are the electronic devices that are used to transmit and receive radio signals. These are electrical conductors for radio waves. Heinrich hertz discovered antennas in 1888. He discovered the antennas to prove the existence of electromagnetic waves. They convert radio frequency electrical current to electromagnetic waves and vice versa. The...
The function of antennas at base stations of cellular radio systems has been proven to be a successful way to increase the performance and the channel ability of personal communication systems. In compare to those technically highly developed base station antennas, the exterior and the practical principle of car antennas with omni directional patte...
Basically a cable is two or more wires bound together typically in a common jacket. Cable TV is a system of providing television network to the consumers. This is done through radio signals transmitted to the televisions through fixed optical fibers. Cable TV can be abbreviated as CATV. Initially it was known as Community Antenna Television origina...
Another name of antenna is aerial. The main function of antenna is to transmit and receive the radio active waves. It is an arrangement of the electric conductors. Antenna converts the radio frequency into electro magnetic waves and vice versa. Main purpose of antenna is television broadcasting, space exploration and radio communication. Usually th...
A rotor is a device which will allow user to rotate the antenna in any direction. The outdoor TV antenna is switched on and off manually. This function is performed by the control unit. The control unit is placed inside house near the television set. The wire carries the power and controls the signals with the help of indoor control unit.
The term grounding means a common return path in electrical circuits. Electricity grounding is nothing but the connection of part of an electrical circuit to an electrical ground. There are three types of grounds, static, RF and electrical. Static grounding is the most difficult. There will no be guaranteed results. The electrical grounding is t...
