If you enjoy FM radio, there's nothing worse than a poor FM signal in your home or apartment. Fading signals and static can take all the enjoyment out of your listening. But you can improve the reception of your FM receiver with a simple folded-dipole antenna design.
Cut a length of 300-ohm flat twin-lead cable that is 4 feet, 7 inches long. Strip the insulation from each end of the wire so that each lead has 3/4 inch of bare wire. Twist together the two wire leads on each end of the cable. Apply your soldering iron to each of these connections, and apply solder to make a solid joint.
Cut one of the leads of the cable with your wire cutters halfway along the length of the 300-ohm cable. Strip the insulation back so that you have 1/2 inch of bare wire on either side of the cut.
Take the end of your RG-6 cable that doesn't have a connector (cut off one of the connectors if both ends do) and strip the insulation back so that you have 1/2 inch of bare wire exposed for both leads.
Solder the leads of your RG-6 cable to the bare wires in the 300-ohm twin lead.
Plug the RG-6 cable's connector into the "antenna" jack of your receiver. Tune in a station, and experiment with placement of the 300-ohm twin lead section until you get the best reception. The antenna will work best when the 300-ohm twin lead is stretched out to its maximum distance.
