Wideband DTV UHF Antenna TV Amplifier Circuit using transistor 2sc3358 – Antenna amplifier for digital tv band
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 antenna tv amplifier or uhf wideband amplifier need to be build inside of a metal box and then connected close to the tv antenna.

PCB layout for Wideband HD TV UHF Antenna TV Amplifier Circuit using transistor 2sc3358
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.
Adjusting is easy, just bring the P1 to the middle and then adjust it untill you obtain the best tv image quality.
