DIY OTA Antenna

Cut your wire hanger in 4 places so you have two bent V-shaped pieces with 8-inch long arms. Discard the hook portion of the hanger. Bend the Vs so there is a 3-inch distance between the two ends. Repeat on three of the five remaining hangers. These will be your antenna reception arms.

Cut the hook and twisted section off the remaining two hangers and straighten the remaining wire into long straight sections. This will be the wire you use to connect the receiver arms.

Screw pairs of the screws and washers 1/2-inch in from the long sides of the board at the following distances from the top of your board: 2-inches; 7 3/4-inches; 10-inches; 13 1/2-inches, and 17 1/4-inches. Do not tighten the screws all the way down. This is where you will attach your wires.

Strip any paint or coating off the hangers where they will attach to the screws so they make metal to metal contact. With a long wire, start under the top left washer, then cross over to the second right washer. Continue under the third and fourth right washers, and then go back across and under the bottom left washer. Repeat this configuration for the second wire, but reverse the sides. Then place one arm under each of the top and bottom two washers on each side, leaving the center ones alone, with the arms pointing out. Screw the 8 washers down snugly with the arms underneath. Do not tighten so much that the wires bend.

Attach the transformer to the two center screws. Screw down the washers to hold it in place.
