6/1/2023 0 Comments Receiver radio antenna![]() The operation of the antenna is less intuitive than that of other transducers. So the function of an antenna is either to send radio waves all over the earth, and even into space, or to receive radio waves from long distances. The shape depends on what you intend to receive or transmit. We see antennas every day: they are in our cell phones, in our cars, in our homes.Īntennas come in many different shapes. by way of electromagnetic energy and radio waves. It is used to transmit music, thoughts, pictures, etc. The receiver uses this electric current to extract the information it contains. The receiving antenna converts the received magnetic field into an electric current. The transmitting antenna converts the electric current generated by the transmitter into an electromagnetic field that is radiated. There are two types of antennas: a Transmitter Antenna and a Receiver Antenna. ![]() The antenna is a transducer, and the conversion takes place between an "electric current" and an "electromagnetic field". ![]() They can easily be disassembled without damaging the antenna in any way.Ī transducer is a device that converts one physical quantity into another. This is to avoid corrosion and the locking phenomenon.Įven after twenty years of exposure to the inclemencies of the harshest climate, the fasteners will remain perfectly functional. Made of brass material and then galvanized, and made larger than the standard one. Our nut is designed specifically for its function: it is not a standard nut, it is manufactured by us. After a year it is impossible to unscrew it. Starting from the simplest detail: the nut used to fix the antenna to the pole, for example.Ī standard steel nut and screw, exposed to the elements, will lock over time. This is why our antennas are real jewels – they shine like platinum, maintain their brilliance over the years and retain their value over time. Our packages are designed with the same care that we design the antennas with, to ensure maximum protection during transport and to reduce the cost of transport itself. It is for this reason that, at TEKO broadcast, we take maniacal care of the packaging phase. To achieve this, we have worked on several fronts:ģ) The quality and type of treatments given to materials Īll this, however, would not be sufficient if, due to mistreatment during transport, the antenna suffered failures or deformations. TEKO antennas are manufactured with the concept of durability in mind.Įvery detail of quality is optimized to ensure that they will work well forever, with no change in performance over the years. Why are TEKO antennas superior in performance and quality to those of our competitors? There are many types of antennas: directional, omnidirectional, yagi, logarithmic, circularly polarized, broadband, tuned, etc.ĭepending on the needs of the broadcaster, it is possible to identify the antenna system that meets their coverage needs.īelow is a description of the main features of our antenna systems, and a guide to help you choose the appropriate model. The type of antenna a broadcaster needs depends on many factors, one of them being the area they need to cover: rural, metropolitan, city, mixed, flat or mountainous terrain, etc. AXON - Compact Stereo Analog FM Transmitter.Your "consumer" radio is not of this class, but it is more convenient to use. High performance radios have no internal antenna, and expect the user to provide signal power at a constant resistance (often 50 ohms) to a coaxial connector. Attaching external long antennas to the telescoping antenna likely disturbs the coupling, resulting in less-than-optimum signal power. Your telescoping external antenna is likely coupled into this component to provide reasonable coverage (not optimum) of the entire span of receivable frequencies. For the lower frequencies, a ferrite-rod component mounted inside the radio provides much of the signal. They expect that the radio antenna will be used "as is". The short antenna provided is far too short for some of the available tuning range of your radio, so the manufacturer has likely included additional internal components to improve its efficiency. And it certainly cannot be extended to 130 m. Although your telescoping antenna can have its length varied, it telescopes mostly to allow convenient storage while not in use. An optimum antenna for the bottom end of the AM broadcast band might be 130 metres long, while an optimum antenna for top-of-FM broadcast band might be 0.7 metres long. The span of frequencies covered is very wide. You have a radio that receives medium wavelength (AM broadcast), short wavelength (shortwave), as well as FM broadcast.
