Antennas intercept waves from radio transmitters that enable you to listen to your favorite radio stations at home, at work or in the car. A standard antenna used to pick up FM radio is perhaps the simplest antenna of all. An FM radio antenna is nothing more than a thin piece of wire inside a metal casing. Whether you want to improve the efficiency of an existing antenna or make an entirely new one, you can do it quickly and inexpensively.
Cut speaker wire to a length of 6 feet. You might not need the entire length, but it's better to have too much wire than not enough.

Strip the coating about an inch off one end of the wire with a pair of wire strippers. This will leave you with bare wire. Wrap the wire around the existing antenna or insert the wire into the hole for the antenna.
Split the speaker wire on the other opposite end with a utility knife to get the two colors of wire separated from one another. Be cautious when doing this to avoid cutting the actual wires.
Hold the wire flat against a wall in any spot you wish. Secure the wire in place with a wire staple or tape. You should have a foot of wire sticking up from the top of the staple or tape.
Pull the two halves of the wire apart until they reach the point of the staple or tape. Spread the two halves apart and secure them to the wall.
Cut off any excess wire, if necessary.
