How to Make Powerful TV Antennas

By Marshal M. Rosenthal

Digital broadcast signals are free for anyone who has a digital antenna attached to their digital television set. You can make your own powerful TV antenna for watching the free TV channels that are broadcast every day. You can make a powerful TV antenna that will work as well, if not better than one bought from a store. You will need metal clothes hangers and a few parts from a hardware store, but no expertise in electronics or TV repair.

Things You'll Need

  • Six metal clothes hangers
  • 12 1/4th-inch diameter metal washers
  • 12 1/4th-inch diameter wood screws
  • 3 foot long 2-inch diameter wood block
  • Tape measure
  • Electric screwdriver
  • Rough sandpaper
  • Pencil
  • Pliers
  • 2 foot long coaxial cable
  • Wire cutters
  • Wire strippers
  • UHF/VHF transformer plug

Step 1

Cut off the tops of the metal clothes hangers using the wire cutters. Straighten out each metal clothes hanger into a metal rod with the pliers.

Step 2

Measure 14 inches from one end of one of the metal rods. Cut the metal rod at the 14 inch mark with the wire cutters. Cut a 14 inch metal rod from the remains of the first metal rod that was just cut. Dispose of the excess metal rod in the trash.

Step 3

Cut an additional eight lengths of metal rods using the wire cutters in the same manner to make a total of six metal assistance rods.

Step 4

Measure seven inches from one end of one of the 14 inch long metal rods. Scrape around the metal rod at the seven inch mark with the utility knife. Repeat this procedure with the other 14 inch metal rod.

Step 5

Place the wood block vertically on a work surface. Measure two inches from the top end of the wood block. Make a mark across the board at the two inch mark with the pencil.

Step 6

Measure down five and three quarter inches from the two inch mark. Make a mark across the board with the pencil. Repeat this procedure. Make an “X” on the left and right side of each of the lines that were drawn on the wood block with the pencil.

Step 7

Place an end of one of the 14 inch long metal rods against the top left side of the wood block. Bend the metal rod to the right when it meets the the “X” at the top left of the wood block. Bend the metal rod to the left after it meets the second “X” on the right side of the wood block.

Step 8

Bend the metal rod to the right after it meets the third “X” on the left side of the wood block. Cut off the excess from the metal rod at the third “X” using the wire cutters.

Step 9

Bend the other 14 inch metal rod so that it looks like the one that was just bent. Cut off the excess from the metal rod using the wire cutters.

Step 10

Scrape the ends of both of the bent metal rods with the utility knife. Scrape the bends in the bent metal rods with the utility knife. Scrape a section in the middle of each of the bent metal rods with the utility knife.

Step 11

Measure seven inches from one end of one of the metal assistance rods. Clamp the jaws of the pliers at the seven inch mark. Bend the metal assistance rod into a “V” shape using the pliers so that the two ends are about three inches apart from each other. Repeat this entire procedure with the other seven metal assistance rods.

Step 12

Place one of the “V” sections of a metal assistance rod onto the topmost ‘X” on the right side of the wood block. Place a metal washer over the “X.” Screw a wood screw through the washer and into the wood block with the electric screwdriver almost all of the way in.

Step 13

Put one of the curved ends of one of the bent metal rods underneath the “V.” Tighten the wood screw into the wood block with the electric screwdriver.

Step 14

Repeat this entire procedure with the next “X” that is across from the first “X” and on the left, putting one of the curved ends of the other bent metal rod underneath the :V: before tightening the wood screw all the way into the wood block.

Step 15

Repeat this entire procedure with the “X” that is directly below the ‘X” that was just used. Repeat this entire procedure with the ‘X” that is across from the “X” that was just done and on the right of the wood block.

Step 16

Wind one of the two exposed ends of electric wire connected to the UHF/VHF transformer plug around the center of the bent metal rod that is on the left side of the wood block. Secure the exposed end of the electric wire to the bent metal rod with a wood screw. Repeat this process with the exposed end of the other electric wire connected to the UHF/VHF transformer plug and the center of the bent metal rod on the right.

Step 17

Attach one end of the coaxial cable to the to the UHF/VHF transformer plug. Attach the other end of the coaxial cable to the coax input on the television set.

Tips & Warnings

  • You can make a base to hold your TV antenna up.
  • Wear work gloves when twisting the metal clothes hanger so that your hands are protected.
