How To Build an FM Antenna

This simple wire antenna works just as well as an expensive model from an electronics store, and it takes just a few minutes to build.


  • Step 1: Tie the exposed leads at one end of the feeder wire to the exposed wires in the middle of the antenna. Make sure the left and right leads don't touch. Cover them with electrical tape.
  • Step 2: Connect the other end of the feeder cable to your FM receiver. If your receiver has a 75-ohm antenna connector, use a 300-ohm to 75-ohm adapter to connect it.
  • Step 3: Place the antenna horizontally, parallel to the ground. The higher you place it, the better your reception. Thread the feeder out a window to place it outdoors.
  • FACT: The average American listens to the radio nearly 19 hours each week.
  • Step 4: Cut a length of wire long enough to reach from your FM receiver to where the antenna will be placed. Strip 1 inch of insulation from each end.
  • TIP: Tack or nail the antenna to a thin strip of wood for easier handling.
  • Step 5: Strip 1 inch of insulation from each end with the wire strippers. At each end, twist the two exposed leads together and cover them with electrical tape.
  • TIP: Solder the leads together for extra durability.
  • Step 6: Find the center of the wire and make a 3-inch cut in the insulation along one of the leads. Then cut through the lead at the center of the slit.
  • Step 7: Strip 1 inch of insulation from the cut lead on both sides of the cut. This is where you will attach the feeder wire.
  • Step 8: Cut a piece of wire 4 feet 11 inches long. This will make your antenna the right length for picking up the entire FM band.
