An antenna is a transducer that transmits or receives electromagnetic waves. In other words you can say antenna converts, electromagnetic radiation into electrical current. In order to minimize the losses in cable, LNB in front of dish antenna is connected that receives the microwave signals and changes the signal in to lower frequency Range. Then the signals are delivered to a signal splitter, commonly known as power divider that divides the signal in to independent path. Then the RF signals are picked by IRD and transmit into digital information after then the signals are fed into the modulator Converts the signals into the channels and then the RF combiner, combines the multiple signals into one output signal which is then amplified by using RF amplifier and transmitted to trunk lines to homes. In homes a local station antenna is also used at the top of the roof to receive the signals. At the end you can say, antenna generally deals in the transmission and reception of radio waves. Antennas are used in systems such as radio and television broadcasting. Eb-ce provides you apical telecom consulting antennas.
