How to Make an FM Antenna
- 1). Cut a 10-foot length of speaker wire.
- 2). Strip about 1 inch of the plastic sheath away from one end of the wire with the wire strippers, and note the copper wires inside.
- 3). Locate the FM antenna hookup on the back of your receiver. This usually says “FM” and has two plastic screw caps underneath.
- 4). Tighten the two exposed ends of the speaker wire under the plastic caps.
- 5). Turn on your receiver and tune it into a radio station that has a bit of static. Find the best area to put your antenna so that the station comes in clearly.
