fm antenna booster circuit


Posted on Feb 5, 2014

This is a low cost fm antenna booster that can be used to listen to program from distant FM stations clearly. The antenna fm booster circuit comprises a common-emitter tuned RF preamplifier wired around VHF/UHF transistor 2SC2570 (C2570). This is the schematic of the simple FM Antenna Booster. Assemble the circuit on a good quality of printed circ

uit board. Adjust input/output trimmers (VC1/VC2) for maximum gain. Input coil L1 consists of four turns of 20SWG enameled copper wire (slightly space wound) over 5mm diameter former. It is tapped at the first turn from ground lead side. Coil L2 is similar to L1, but has only three turns. Pin configuration of transistor 2SC2570 is shown in the fm antenna booster schematic.
