The satellite antenna is an artificial satellite, which is placed in space. The main purpose of satellite antenna is to serve communication. It solves the purpose of reconnaissance with the use of radio at microwave frequencies. An earth station is located on the ground, which use to transmit the radio waves. The satellite antenna use geosynchronou...
Antennas are the transmission devices used to transmit audio and visual frequencies in the form of electromagnetic waves. The maximum use of antennas is in radios with special antennas available for satellite radio reception. The antennas are designed according to purpose and accordingly there are exclusive home antennas designed for satellite radi...
An antenna that is able to receive signals from many directions is called a multi directional antenna. There are many size and shapes of multi directional antennas. They have different features. There are mainly two types of multi directional antennas, one being the indoor antenna and the other being the outdoor antenna. The indoor antennas can be ...
It is an electronic device used to transmit and receive radio signals. A directional antenna is an antenna that radiates greater power in one or more directions. This allows increased performances on transmit and receive and receive and reduced interference from unwanted sources. All the antennas are slightly directional. The normal antennas have a...
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...
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...
Antennas are the electronic devices used for transmission and reception of electromagnetic or radio waves. Basically an antenna is an arrangement of aerial electrical conductors. They convert radio frequency electrical currents into electromagnetic waves and vice versa. Antennas have wide range of uses. They are used in the systems such as radio an...
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.
Sits ups are a basic form of strength training exercise. It the most common and prominent exercises for the abdominal muscles. The main objective of this exercise is to work out the abdominal muscles to the maximum extent. There are many people who do as many sit ups each day in an attempt to gain a six pack. However in order to gain the maximum be...
It is not necessary to warm up only before participating in sports or exercising, even though they are traditionally done like that. The sole purpose of warm up is to gradually increase the intensity in the physical activity. Likewise before running or playing an intense sport a slow jog to warm the muscles and increase the heart rate. However the ...
