This is a simple active antenna booster. This amplifier will pull in all distant FM stations clearly. The circuits is configured as a common-emmitter tuned RF preamplifier wired around VHF/UHF transistor Q1. Input coil L1 consists of four turns of 20SWG enamelled 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. Adjust input/output trimmers (VC1/VC2) for maximum gain.
Use this fm antenna amplifier in areas where the signal reception of FM stations is too bad. This circuit is just the right thing to do it. It is designed

61 - Tri-band Delta Loop Antenna for 80m - 40m - 30m Wire Antennas for Ham Radio
Here we are presenting a long range FM transmitter that can cover a reasonable distance of 5 kilometers / 3 miles and beyond with a one watt RF power with full circuit details, bill of material and testing procedure. With 12 volt DC it will deliver 1 watt RF power. With Yagi antenna, looking like early days of TV antenna with aluminum pipes at both at transmitter and receiver end looking each other at line of sight distance, the range can be up to 5 km / 3 miles.
