Wideband UHF Amplifier - Antenna TV Amplifier Circuit

Posted on Feb 4, 2014

This UHF wideband amplifier(Ultra High Frequency amplifier) has a total gain of 10 to 15 dB in the 400 850 MHz domain frequency so it can be used where the tv signal is weak. For this UHF antenna tv amplifier to work correctly you need to cut the components pins as short as possible. C1, C2, C6, C7 are SMD type ( surface mounted ). This antenn

a tv amplifier or uhf wideband amplifier need to be build inside of a metal box and then connected close to the tv antenna. The power supply is a simple 12V stabilized source. The antenna tv amplifier can be connected directly to the power supply thru coaxial cable of the tv antenna but you need a 10 100uH coil on the alimentation line. The tv set will be connected to the uhf amplifier thru a small coupling capacitor.
