Wiring Schematic Diagram

This is an UHF bandage TV antenna preamplifier circuit With 15dB accretion to body easily. It is formed based on BF180 UHF Transistor. The aboriginal date is an bandage canyon clarify complete by the C1, CV1, L1, L4, C7 and C3, the additional date is a base-common voltage amplifier with low ascribe impedance to match. Body the L1 ~ L4 as air amount braid to access aerial Q-Factor. After assembling, backpack it into a able brownish box and affix the arena of the ambit to the box to abate babble effect.
