Antennas are the electronic devices that are used to transmit and receive radio signals. These are electrical conductors for radio waves. Heinrich hertz discovered antennas in 1888. He discovered the antennas to prove the existence of electromagnetic waves. They convert radio frequency electrical current to electromagnetic waves and vice versa. The...
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...
A cell phone is an electronic device that is portable for talking over long distances. Cell phone connects to the cellular network of the site of cell which is further connected to the telephone network of public. Mobile phone offers many services other then acting as a phone. It offer the services like SMS, access to internet and also the MMS faci...
Being able to talk on a handheld gadget without wires crossways the world is really a great achievement in technology. Few people stop and imagine about this minor miracle. However, when someone stuck somewhere unable to make a call because of a poor cell signal, the appreciation for this technology can be tested. Regrettably, cellular service prov...
Basically a cable is two or more wires bound together typically in a common jacket. Cable TV is a system of providing television network to the consumers. This is done through radio signals transmitted to the televisions through fixed optical fibers. Cable TV can be abbreviated as CATV. Initially it was known as Community Antenna Television origina...
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...
Another name of antenna is aerial. The main function of antenna is to transmit and receive the radio active waves. It is an arrangement of the electric conductors. Antenna converts the radio frequency into electro magnetic waves and vice versa. Main purpose of antenna is television broadcasting, space exploration and radio communication. Usually th...
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.
Antennas are the electronic devices that are used for reception and transmission of radio waves. In other words it is an arrangement of aerial electronic conductors that are designed to receive and transmission of radio waves. Antennas convert radio frequency electric currents into electromagnetic waves. Antennas are used in all most all the electr...
The term grounding means a common return path in electrical circuits. Electricity grounding is nothing but the connection of part of an electrical circuit to an electrical ground. There are three types of grounds, static, RF and electrical. Static grounding is the most difficult. There will no be guaranteed results. The electrical grounding is t...
