The antennas are the starting point of the broadcasting system. Antennas form the basic device for the working of radios and televisions. They are also used in areas like radar and space communication, under water operations and even for under ground tasks. However, it is necessary to check the functionality of the antennas on the basis of certain ...
The very new satellite antenna, approved by Satellite Radio has been
specially designed to receive signals from three satellites and other network of
ground-based repeater transmitter. Satellite antennas are exceptionally
sensitive and delicately specified to assist reception of satellite signals
under a variety of conditions across the cou...
Antennas are electronic devices used to transmit and receive radio signals. Antenna is an arrangement of aerial electrical conductors. Heinrich hertz discovered antennas in 1888. For the first time he used the antennas to prove the existence of electromagnetic waves. The antennas convert radio frequency electrical current into an electromagnetic wa...
The television sets are incomplete without antennas. It is the antennas
that transmit the signals into electromagnetic waves and broadcast the visuals
on the television. However, the television antennas are powerful and need to be
handled with great care and caution. The individuals may suffer from physical
injury if they do not handle the ...
Amplifier is an electronic device using transistors or electron tubes. This is used to produce and amplification of an electrical signal. It also increases and restores the strength of the signals passing through it. It involves the controlled conduction of electrons especially in a gas or vacuum or semiconductor. An amplifier uses a small amount o...
Directional antenna is an electronic device used to transmit and receive radio signals. This antenna radiates greater power in one or more directions allowing for increased performance on transmit and receive and reduced interference from unwanted sources. Mainly there are two types of antennas indoor and outdoor antennas. The indoor antennas have ...
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...
