Hello guys, I searched for a simple tv signal booster and I found a circuit, it was written this circuit is for 3-900 MHz amplifier with 20 db gain, after two weeks of trial Finally I failed because after installing device between antenna and tv there is no signal, my circuit is here please take a look at it and help me what is wrong please.
Parts:
R1 = 120 Ohm (brown, red, brown)
R2 = 1,5 KOhm (brown, green, red)
R3 = 270 Ohm (red, violet, brown)
R4 = 82 KOhm (gray, red, orange)
C1,C5 = 100pF (ceramic)
C2,C3 = 1nF (ceramic)
C4 = 2,2pF (ceramic)
D1,D2 = 1N4148 diode
Transistor = BFR90, BFR91, BFW92
Misc = PCB, 6pins, solder, 9V battery clip
L1,2:diameter : 5mm
wire thickness : 0,5mm
turns : 8
Input 4 and ground
Output 1 and ground
Positive pole 3
Negative pole 2
Thanks and sorry for my English.
