Transmitting And Receiving Aerial

Telecommunication is continually evolving to meet the growing demand for better and most sophisticated communications for both the commercial and domestic purpose. Aerial is the foremost electrical communication, broadcasting and transmitting device that is used in sending and receiving radio or television signals. The applications of these aerial systems is range to wider dimension in most signal communications like in aerospace, defense, air and naval requirements. The non-directional and omnidirectional aerials are widely used to send or receive signals equally in all directions. Dipole aerial is consisting of half a wavelength long and two rods connected to a transmission line at the center. Aerials offered with video transmission systems use radio waves for different frequency ranges. They use fm transmission systems that produce a high quality picture even in low signal strengths. Fm aerials are made to receive radio signals and television signals with wide distance ranges.
