The quality of this VHF booster seems not better than the one sold in electronic stores. Look at the picture! Only a few parts needed to finish it. Anyway, the result was more than I expected. Most of VHF local and foreign TV (Singapore and Malaysia) can be enjoyed clearly. I lived in north part of Indonesia, in a three angle border between Indonesia, Singapore and Malaysia. That's why TV channels from those countries can be captured easily.
The basic part of this schematic is TR1 (C2570), specially designed for amplifying VHF and UHF signal. No coil needed for this project …
You may omit S2, as per PCB diagram, I have deleted S2 to connect the antenna and TV set permanently through the booster.
