Preparing the Wire
Before you can start creating your TV antenna, you need to prepare the wire. This involves stripping the insulation from the ends of the wire and then twisting the individual strands together.
Stripping the Insulation
To strip the insulation from the ends of the wire, you can use a wire stripper or a sharp knife. If you are using a wire stripper, simply insert the wire into the stripper and squeeze the handles. The stripper will cut the insulation and remove it from the wire.
If you are using a sharp knife, be careful not to cut the wire itself. Hold the knife at a 45-degree angle to the wire and gently score the insulation. Once you have scored the insulation, you can peel it off the wire.
Twisting the Individual Strands
Once you have stripped the insulation from the ends of the wire, you need to twist the individual strands together. This will make the wire stronger and more conductive.
To twist the strands together, simply hold the ends of the wire in one hand and twist them together with the other hand. Twist the strands until they are tightly bound together.
| Wire Gauge | Number of Strands |
|---|---|
| 18 AWG | 19 |
| 16 AWG | 26 |
| 14 AWG | 37 |
| 12 AWG | 61 |
Creating the Dipole
The dipole is the heart of the TV antenna, so it’s important to make it correctly. Here’s how to do it:
- Cut two pieces of wire. Each piece should be 1/4 wavelength long. For UHF, this is about 7 inches. For VHF, it’s about 28 inches.
- Strip the ends of the wire. About 1/2 inch of bare wire is enough.
- Bend the ends of the wire into a loop. You’ll need to flatten the end of the wire and then bend it around a pair of pliers to form a U-shape. Make sure the loop is large enough to fit over a bolt or nail.
- Solder the loops to the center conductor of the coaxial cable. The center conductor is the wire that runs down the middle of the cable. Make sure the solder joints are clean and strong.
- Spread the dipole wires apart. The distance between the wires should be about 1/2 wavelength. For UHF, this is about 3 inches. For VHF, it’s about 14 inches.
- Connect the outer conductor of the coaxial cable to the ground plane. The ground plane is a metal surface that helps to reflect the TV signals back to the antenna. You can use a sheet of aluminum foil or a piece of metal roofing for the ground plane.
Here is a table summarizing the steps for creating the dipole:
| Step | Instructions |
|---|---|
| 1 | Cut two pieces of wire 1/4 wavelength long. |
| 2 | Strip the ends of the wire 1/2 inch. |
| 3 | Bend the ends of the wire into a U-shape loop large enough to fit over a bolt or nail. |
| 4 | Solder the loops to the center conductor of the coaxial cable. |
| 5 | Spread the dipole wires apart 1/2 wavelength. |
| 6 | Connect the outer conductor of the coaxial cable to the ground plane. |
