15db uhf tv antenna booster circuit


Posted on Feb 7, 2014

This is a circuit for antenna UHF TV that can be give 15dB preamp. This circuit is built by transistor and low components. This is the figure of the circuit. The circuit above is formed based on BF180 UHF Transistor. The first stage is a band pass filter constructed by the C1, CV1, L1, L4, C7 and C3, the second stage is a base-common voltage ampli
