DIY High Gain TV Antenna
- 1). Place the wood vertically on the table. Measure 2 1/2 inches down from the upper left corner of the wood. Measure 1 inch in from the 2 1/2-inch mark. Make a dot with the pencil. Measure down 2 inches from the dot and make another dot. Repeat this another two times.
- 2). Place a metal washer over each of the dots on the wood. Partially screw a wood screw into each of the dots (halfway) with a Phillips screwdriver. Wind an end of one of the two solid-core electric wires around the topmost left screw. Run the wire over to the screw beneath and to the right of the first screw. Run the wire over to the screw beneath and to the left of the second screw. Repeat this action an additional two times and wind the end of the wire around the screw. Repeat this entire procedure with the other solid-core electric wire, only starting at the topmost right screw. Wrap a strip of electrical tape around one of the wires where it crisscrosses the other to insulate one from the other.
- 3). Place the bent section of each rod around one of the screws on the wood; the bent ends of the rods that are on the left side of the wood are facing left while the bent ends of the rods that are on the right side of the wood are facing right. Screw the screws in with a Phillips screwdriver.
- 4). Wind one end of the two wires attached to the "Balun" coax transformer around a section of the solid-core electric wire that is on the left side of the wood. Repeat this procedure with the end of the other electric wire attached to the "Balun," only with the solid-core electric wire on the right side of the wood. Wrap a strip of electrical tape around each of the "Baluns" wires to adhere it to the solid-core electrical wire.
- 5). Screw an end of a coaxial cable into the connector on the "Balun." Screw the other end of the coaxial cable into the "Ant in" or "Coax in" on the back of the television set. Place your DIY high-gain TV antenna outside, against the side of your home or a tree where there is an unobstructed view of the sky. Rotate the rods of the antenna so that they are facing the horizon.
