Step-by-Step Guide
-
Step 1: Prepare a wooden board.
It should be 1x3 inches (2.54x7.62 cm) or 2x3 inches (5.08x7.62 cm).
It should be 22 inches (55.88 cm) long.
Going from left to right with the board laying horizontally, mark lines at the 2 inch (5.08 cm) mark, the
7.25 inch (18.42 cm) mark, the
12.5 inch (31.75 cm) mark, and the
17.75 inch (45.09 cm) mark.
Use a marker or a pencil.
Mark 2 dots on each line that are evenly spaced. -
Step 2: Cut 8 sections of copper wire.
Each section should be 14 inches (35.56 cm) long. , Each should be bent so that each side is 7 inches (17.78 cm) long.
The gap between each side should be 3 inches (7.62 cm) long.
Each wire should resemble a "V" when you are finished. , Attach the center (bent portion) of each wire to the dotted areas of the board using screws and washers.
When finished, each v-shaped wire should extend outward from the board. , Use the remaining portion of the wire for this.
The bent portion of the v-shaped wires should be intersected once each.
The wires should not touch each other.
Be sure that at least 1 of the wires that you weave is insulated.
Vinyl insulation will work well.
When finished, the wires should resemble 2 "X" shapes that connect the first and second and the third and fourth sets of v-shaped wires, respectively.
Two horizontal lines should connect the "X" designs between the second and third sets of v-shaped wires. , Two reflectors should be evenly spaced on the back of the board.
Each reflector should be 15x9 inches (38.1x22.86 cm).
Use screws to complete this task.
The reflectors should not touch the v-shaped wires. , This is a transformer that can be purchased on the Internet or at an electronics retailer.
Follow the instructions that come with the balun. , Use a coax cable, which can be purchased on the Internet or at an electronics retailer.
Follow the instructions that come with the coax cable. -
Step 3: Bend each section of wire.
-
Step 4: Attach the v-shaped wires to the board.
-
Step 5: Weave 2 wires on the board.
-
Step 6: Attach reflectors (grill screens) to the board.
-
Step 7: Attach a balun to the 2 center sections of wire.
-
Step 8: Attach the antenna to a HD television.
