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 ...
Television antenna signals are strongest and reception is generally the best when the station's transmitting tower is in clear line of vision with the home receiving the broadcast. Mountains, buildings or trees that block this line of sight tend to weaken and degrade the received signal. The signal also becomes weaker as it travels further from the...
Basically an antenna is an aerial. It has the main function to transmit and receive the radio waves. It is an electronic device that converts the radio frequencies into electromagnetic waves and vice versa. Indoor antennas are the antennas used inside the home or any other such place. There are varieties of indoor antennas. All the electronic de...
Antennas are the electronic devices used to transmit and receive radio signals. They are the important and essential component for a home. The antennas are responsible for providing good and proper signals. There are many types of home antenna systems are available.
1. Normal antennas:
These are the antennas usually used to receive ra...
Antenna is an electronic device. Basically it is an aerial electronic conductor. Heinrich Hertz discovered an antenna in 1886. The antennas convert the radio frequency electric current into an electromagnetic wave. Antennas are used in radio and television broadcasting. They also have an application in communication systems, radar and space explora...
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...
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...
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.
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...
