Quick, Makeshift HDTV Antenna

Picture of Quick, Makeshift HDTV Antenna
How to build a makeshift HDTV antenna from mainly old coat hangers.Credit for the antenna design goes to the Solid Signal Blog. I don't claim to have invented this, but I see that there aren't many quick, makeshift antenna tutorials here on instructables, so I just thought I'd try to share their setup.Parts needed:
1. 75 to 300 Ohm Matching Transformer ($1 to $3 on Amazon.) (It should adapt from twin lead to coaxial)
2. Two #6 or similar screws.
3. Small piece of wood board
4. Coax cable.
5. Two metal wire coat hangers.
6. If coat hangers are insulated, you will also need a wire stripping tool, if not, just use sandpaper to remove paint coating as needed.

Step 1: Cut the coat hanger wire to size

Cut hangers into two 20 inch pieces of wire and straighten out the wires as much as you can.

Step 2: Strip or sand wire.

If the wire you're using is insulated, use your wire cutter tool to strip a 1 inch section off the middle of each of the pieces of wire. If your coat hangers were just painted and not insulated, just sand a 1 inch section in the center of both pieces of wire so that the metal is exposed well.

Step 3: Fasten the parts together.

Bend each of the two pieces of wire like in the attached picture, and cut the wire so that each line is 8 inches long. then, use the screws to pin the two leads of the matching transformer to the wooden board so that the wire can conduct into the transformer/coax adapter. The distance between the two screws should be around 1 inch.
