How to Make a Beam Antenna From Inverted V’s

Place the plastic rectangle on a work surface horizontally. Measure across the rectangle, starting from the top-left edge, with a ruler. Make a mark on the rectangle with a pencil every 2 inches, for a total of four times. Repeat this procedure, only starting at the bottom-left corner.

Screw a metal screw halfway through each of the pencil marks with a Phillips-head screwdriver. Place the "V" end of an inverted metal rod against each of the screws. Rotate each rod so that those on the screws farthest from you are facing up and those on the screws closest to your are facing down.

Wind the end of one of the two uninsulated strips of wires around the screw on the upper-left corner. Run the wire down to the second from the left screw on the bottom. Run the wire up to the third from the left screw on the top. Run the wire down to the rightmost screw on the bottom. Wind the wire around this screw.

Wind the end of one of the other uninsulated strip of wire around the screw on the bottom-left corner. Run the wire up to the second from the left screw on the top. Run the wire down to the third-from-the-left screw on the bottom. Run the wire up to the rightmost screw on the top. Wind the wire around this screw. Tighten all of the screws.

Place a piece of insulating electrical tape around one of the wires where it touches the other. Wind the uninsulated end of one of the two wires from the TV transformer around one of the uninsulated wires. Wind the uninsulated end of the other wire from the TV transformer around the other wire.

Cover each of the two wires that are wrapped around each other with a strip of insulating electrical tape. Screw an end of a coaxial cable into the coax socket on the TV transformer. Screw the other end of the coaxial cable into the "Ant in" socket on the back of the digital television.
