Good or images and sound from a TV in the received interpretation of the TV station is influenced by several factors. Can of location, quality TV and could also be from a lack of good quality antenna.
You live in a place that its very poor television reception,
for example, in the countryside or even if you live in the city could be your trouble catching television broadcast reception it is usually because you are far away from the location of the city television transmitter station or other reasons because it is blocked by mountains or valleys. For those who live in big cities like Jakarta, for example, does not require a booster because by installing external antennas with a height of 5 meters already get 14 private television stations.
In rural areas far from the base station or a relay station transmitter used to use an outdoor antenna or satellite dish to catch a favorite TV broadcasts. Since the parabola is still expensive usually they use the outdoor antenna amplifier plus antenna booster called.
Below I include schematic drawings Booster Antenna TV series. Please learn and practice to increase the sensitivity of perception takes your TV signal.
The circuit shown above is from the TV antenna booster based transistor BF180. Booster Antenna TV series operates on UHF band and has a gain of 15dB. Capacitors C2, C3, C4, C5 and inductor L3, L4 form a UHF band pass filter. The input signal is fed to the emitter of Q1 through this filter. Resistors R2 and R3 to transistor Q1 deviant who transferred in a common base configuration.
