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 ...
The omni directional antenna is an antenna system that radiates power uniformly in all directions. The only 3 dimensional omni directional antenna is the isotropic antenna, a hypothetical construct derived from actual antenna radiation patterns and used as a suggestion for specifying antenna gain and radio system effective radiated power. Practical...
It is an electronic device used to transmit and receive radio signals. A directional antenna is an antenna that radiates greater power in one or more directions.

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...
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...
