UHF amplifier electronic project using transistor

Using electronic diagram below can be design a UHF amplifier useful in situations where the TV signal is weak. The UHF amplifier has a gain of 10-15 dB in a frequency range between 400 and 850 MHz.
To obtain optimum performance and good reliability, the PCB tracks should be covered with tin.
At each disc capacitors C4, C5, C8 and C9, by one of the girls is glued directly on board.
