Saw a length of 2-by-4 to 41 inches.
Snip the tops off 10 unpainted wire hangers using wire cutters. Straighten each of the hangers. Cut eight wire lengths to 14 inches, and two wire lengths to 21 inches.
Bend each 14-inch wire segment into a "V" shape. Keep the 21-inch wires for later use.
Mark four positions on both sides of the narrow surface of the 2-by-4 with a marking pen. Make the first two marks on both sides of the narrow surface six inches down from the end of the board. Make two more marks seven inches below the first marks. Make two additional marks at 20 inches down the board, and the final two marks at the 27 inches. Make an X at all marks one half inch in from the wood edges.
Drill pilot holes using the power drill with a 1/8-inch drill bit at each marked point on the 2-by-4.
Attach each of the 14 V-shaped wires to the board. Wedge the bend of each V under a wood screw and metal washer. Use a drill with Phillips drill bit or Phillips screwdriver to tighten each hanger section. Be sure none of the washers touch.
Attach the two 21-inch hanger lengths to the V segments. Secure this hanger with the first V segment on the left. Tighten it firmly beneath the washer at that position. Then route this hanger diagonally to the second V on the right side. Continue on to the third V on the right side, tightening this wire under each washer. The final connection crosses back to the left side, connecting with the fourth V segment on the left. Repeat this sequence for the remaining 21-inch wire length, beginning at the top V position on the right.
Insulate the two 21-inch interconnecting wires with electrical tape where they cross one another.
Attach the UHF/VHF transformer, aka balun, to the two interconnect wires using wood screws and metal washers between the second and third V sections. Ensure all screws are tightly bound.
Confirm that all V segments are the same length. Also confirm that the spread of each V is three inches at the wire ends.
Attach a 75-ohm coaxial cable to the UHF/VHF transformer, and attach the other end of the cable to the antenna/cable input on an LCD or plasma TV. Set the television to cable/antenna input, and move the antenna on a horizontal axis until the strongest signals are present.
