How to Make a TV Antenna With a Potato

Save

For those not privileged enough to enjoy the clear picture-perfect images displayed through cable television, we must muss and fuss with cables, antennas, bunny ears, knobs and strategic room locations to get the picture to come in just right. Then we change the channel and have to start all over again. If you are looking for more affordable ways to improve your signal, it's time to try potatoes. Read on to learn how to make a TV antenna with a potato.

Things You'll Need

  • Large fresh potato
  • Coaxial cable
  • Paring knife
  • Purchase a large fresh potato and scrub it throughly, removing any pieces of mud and grime; however, do not remove the peel. Allow the potato to dry completely before using it as a TV antenna.

  • Press one end of a coaxial cable into the center of the potato, being careful not to bend or break the metal point inside. Press the metal cable adapter just firmly enough to create a circular indentation in the potato. Remove the adapter and use the circle as your guide, using a small paring knife to cut a hole about 1/2 inch deep. To ensure the cable holds tightly, it is better to cut the hole slightly smaller than the adapter ring than too big.

  • Push the coaxial cable's adapter firmly into the hole as far as it will go. If the adapter is a bit loose, you can use extra potato shavings from the cut out hole to wedge into open spaces, holding the adapter in place.

  • Plug the opposite end of the coaxial cable into the antenna port on the back of your TV, rest your potato on top of the television, and viola. Keep an eye on your potato, swapping it out for a new one when it begins to brown.
