- 1). Place one piece of wood on a flat surface with the 3 inch-wide side facing up and the 40 inch-length extending away from you. Run your tape measure down the length of wood one-inch from the left edge. Place marks at 2, 8, 14 and 20 inches, starting at the edge furthest away from you. Do the same down the right side of the wood one inch in from the edge. You will end up with two rows having four marks centered ½ inch from the middle.
- 2). Cut eight brazing rods down to 14 inches with your wire cutters. Bend each piece in half forming a "V" shape with a three-inch gap at the open end. Each leg of the "V" should measure seven inches.
- 3). Place a washer over a screw and turn the screw half way into one of the marks on your wood with the screwdriver. Do the same for the remaining seven marks. This is where you will attach the "V" shaped brazing rods.
- 4). Bend the tip of one of the copper wires with the pliers to fit under the top left-hand screw. Align the wire so it runs down the row of screws on the left side of the wood. Slide one "V"-shaped brazing rod under the washer. Tighten the screw with the open end of the "V"-shaped rod pointing straight out from the wood on the left side. Using the second copper wire, repeat the process at the top right-hand screw.
- 5). Slide a "V"-shaped rod under the remaining washers and screws on the left and right sides. Take the copper wires from the top screws and cross them over. Slide the wire under the second washer and screw on the opposite side of the wood. Tighten the screw with the open end of the "V"-shaped rod pointing straight out from the wood on the left side. Run the copper wire under the third washer. Tighten the screw with the open end of the "V"-shaped rod pointing straight out from the wood.
- 6). Cross the two copper wires over to the opposite side of the wood. Slide the copper wire under the remaining washer and screw. Tighten the screw in the same manner as the other screws. You will have four bow-tie shapes in a row. Cut off the excess piece of wire with your wire cutters.
- 7). Lift up the top wire where it crosses the other wire with your fingers. Wrap electrical tape around it to insulate it from the wire underneath. Do the same for the other section where the wires cross. If the wires make contact, the antenna will not work properly.
- 8). Screw a washer loosely into position over each copper wire mid-point between the second and third screw. Attach one wire of the 75-ohm VHF/UHF transformer balun (cable adapter) to the screw under the left-hand washer and tighten the screw. Do the same using the remaining wire from the transformer balun attaching it to the right side washer and screw.
- 9). Turn the antenna over with bow ties facing the table and screw the two 15-by-9 inch cooling racks to the wood. One rack will line up with the top two bow ties and the other with the bottom two bow ties. This is a reflector to send some missed signals back to the bow ties for a stronger signal.

Repeat steps one through nine. Do not attach anything to the loose screws and washers where you attached the 75-ohm transformer balun on the first antenna you made. - 11
Make a two-inch cut down the flat center of the wire at each end to separate the wires. Scrape off one inch of the plastic coating at each end of the wires. From one end of the wire, attach one of the wires to one of the screws on the second antenna and tighten the screw. Attach the other wire on the same end to the remaining screw and tighten the screw.
Connect the other end of the wire to the 75-ohm transformer balun connector screws of the first antenna. - 12
Setup one antenna near the top of your antenna mounting pole, making sure it's secured to the pole so it won't move. Set up the second antenna below it at an angle of 90 degrees from the first. In this way the antennas will receive a full 360 degrees of signals from around your city.
Attach the mounting pole to a heavy base or fix it to a wall. Connect the TV cable to your 75-ohm transformer balun and you are done.
