TV antenna is a signal from the antenna to the amplifier to the antenna televisi.adanya plane or electromagnetic wave signals can be received or transmitted. Unit strength in focusing electromagnetic waves are dBi (decibels isotropic) and in general there are two types of antenna that is directional and omni directional. Directional Antenna is a type of narrow antenna beam width, atinya only has a small emission angle but more focused. Examples of such antennas are directional antennas satellite dish, pan Bolic, grid, yagi, Sectoral Antenna and so on. Omni directional antenna is an antenna type that has a wide beam width beam angle larger, but the distance is shorter. So this antenna is used to transmit or receive signals in all directions. Examples such as an antenna for the transmitter hospot, Antenna HP, Dipole san forth.
