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...
The transmission of TV programs to the home and office is via coaxial cable. Since they were already wired into so many homes, cable TV companies have had great success selling Internet access. Unlike the other cable service, Internet via cable does not have distance limitations. Cable television or community antenna television is a system of provi...
The satellite radio antenna is a basic hardware component. Three components are required to receive the signals from the preferred radio service provider. It is the fact that all the providers offer the same services and technologies even the hardware used are also the same. Antenna is used to transmit the signals from the satellites, which will pr...
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 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...
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...
There are many indoor concrete buildings with no windows within 35 feet of the cellular phone units. Criteria for these new locations include low or unsound signal without the antenna booster installed. Tests conducted for indoor functionality of the antenna booster spanned over a period of time of no less than a couple of months. The rationale for...
The elements of the antenna array means the collection of all the similar radiation and elements related to the antenna, where the counting of the elements starts from 1 till N number. The similarity of the elements is judged on the basis of the same frequency, which means to derive voltage of each element one has fixed amplitude and phase angle. T...
