How to Improve FM Radio Signal With Wire
Nothing is worse than listening to your favorite song on the radio and having static overtake the airwaves. If you in a car, there's not much you can do but change the station. But if you're at home, or somewhere else that isn't mobile, an easy solution is to make your own wire antenna to attach to your radio. Of course, make sure you're utilizing the antenna your radio already has by making sure it's fully extended and you've tried moving it in various locations to get the best signal.
Things You'll Need
- 30 feet of 300-ohm twin-lead wire
- Soldering iron
- Electrical tape
- Wire strippers
- Wire cutters
Building Your Antenna
Cut 20 feet off of your ohm twin-lead wire and place the extra wire aside. You'll need the extra wire later.
Strip both ends of your 20-foot wire with your wire stripper so 1/2 to 1 inch of bare wire is exposed per end. The exposed wire acts a conduit to receive the radio station's air waves and transmit them to your radio.
Twist the two exposed wires on each end together tightly. Use your soldering iron to solder each end of your exposed wires.
Strip both ends of the remaining 10-foot length of ohm twin-lead wire with your wire strippers in the same manner as the other wire. You'll be connecting the two of them in a moment.
Strip away a 2-inch, very thin section out of the middle of the 20-foot ohm twin-lead wire. You want to be sure you only expose one wire in the middle, and not both of them.
Twist together one end of the exposed wire on the 10-foot wire and the exposed wire in the middle of the 20-foot wire. Solder the wires together, and bind that section with electrical tape.
Connect the antenna to your radio with the ends of the exposed wire on the 10-foot ohm wire. Make sure that end was not twisted together or soldered. Now tack up your wire as high as possible, even going outside a window to climb up the side of the house for best reception.
