TV antenna booster


Posted on Feb 5, 2014

The circuit shown here is of a TV antenna booster based on the transistor BF180. The circuit operates in the UHF band and has a gain of 15dB. Capacitors C2, C3 C4, C5 and inductors L3, L4 forms a UHF band pass filter. The input signal is fed to the emitter of Q1 through this filter. Resistor R2 and R3 biases the transistor Q1 which is wired in the
