Are you tired of missing out on your favorite shows? 

Are you struggling with expensive monthly TV subscriptions?

If you want to get out of your current predicament, start by making a homemade TV antenna.

Because a TV antenna will help you get free HD channels. Making it yourself may be more satisfying compared to buying an expensive TV antenna.

In this article, we have compiled two TV antenna-building guides for you to choose from for different needs. Reward yourself for watching HD TV channels with a homemade TV antenna, and you'll never miss your favorite shows again.

What Materials Can be Used to Make a TV Antenna?

The antenna is used to receive and improve the radio signal of the TV. Instead of spending a lot of money on antenna products, you can make your own and get the same results. And your first headache will be selecting a suitable material. Generally speaking, three kinds of materials are ideal for making a TV antenna: iron, aluminum, and electroceramics.

● Iron: Iron is not the best material for antennas, but it is cheap and suitable for receiving TV wavelengths. Metal hangers can be used as iron products to make antennas.

● Aluminum: Lightweight and cheap, aluminum is one of the best materials for antennas. Aluminum can be used in foil or made into a stronger mesh. Due to the fact that aluminum oxide forms naturally when exposed to sunlight, aluminum mesh is frequently used for outdoor antennas.

● Electroceramics: Electroceramics are specialized forms of conductive materials. They can be used as TV antennas, receiving wavelengths. But this kind of material is rare in daily life.

6 Steps to Make a Simple TV Antenna

If you plan to make a simple TV antenna to deal with some emergencies, you only need to prepare the following items:

● Metal hanger

● Sandpaper

● Metal paper clips

● Tape

With the above items ready, you can make a simple TV antenna by following these 6 easy steps:

1. Remove the coating from the hanger: Most hangers have a coating on them which can affect signal transmission. Use sandpaper to rub the surface of the metal hanger hook until you see bare metal.

2. Unhook the hanger: Grasp the hanger's hook and open the connection. In this way, the hanger becomes a curved iron wire. 

3. Locate the coaxial connector and apply tape: Look on the back of your TV to find the coaxial connector labeled "Antenna In" or "Cable". Put a piece of tape on the end of the coaxial connector. This is to prevent the paper clip from shorting the connector.

4. Bend the paper clip and install: Open the prepared paper clip and bend it like an "S" shape. Bend the short end at a right angle and push the bent portion into the small hole in the center of the coaxial antenna connector.

5. Hang the hanger: Hang the unfolded hanger on a paper clip.

6. Channel Search: Use the TV's auto-tuning function to scan for channels.

According to the above steps, a simple antenna is ready, and its quality may not be very good, and it cannot receive too many channels. But in an emergency, it is indeed a handy substitute.

What If You Want to Make a HD TV Antenna?

If a simple antenna can't meet your needs, you can also make a high-definition one. Making a high-definition antenna requires more materials, and the production process is more complicated, but it will help you search for more clearer channels.

Let's take a look at the materials needed to make a high-definition antenna:

● 136 inches of uninsulated aluminum wire, two 34-inch aluminum wires

● Wire cutters, electric drill, 10 screws, 10 metal washers

● 32-inch plank

● Electrical tape

● Matching transformer, coaxial cable

● Soldering iron

After preparing the above tools, you can start to make the high-definition antenna.

  1. Cut 8 aluminum wires: Use wire cutters to cut 136 inches of uninsulated aluminum wire into 8 equally spaced individuals.

  2. Bend the aluminum wires into a V shape: Bend all eight aluminum wires in half and V shapes. Aluminum wire ends 3 inches apart. 

  3. Drill the boards: Use a power drill to drill bottomed holes every 8 inches in a 32-inch panel. 10 spots are evenly distributed on both sides of the board. The diameter of the hole is slightly smaller than the diameter of the screw. (Make sure the holes on both sides line up with each other)

  4. Install the screws and washers: Align the center of the metal washers with the holes in the wood and slowly turn the screws into the holes until they snap into the wood. (Don't fully tighten the screws, as you'll need clearance for the wires)

  5. Wrap the antenna around the screw: Put the bent antenna in turn bottom under the metal washer. Make sure the bent part of the wire is tightly placed on the bottom of the screw to keep it from moving. Make the wire opening point outward. (Don't let the individual antennas touch each other, as this will negatively affect the signal strength)

  6. Thread aluminum wire through the screws: Wrap the ends of the two aluminum wires around the top two screws of the board. Cross over to the opposite side after passing the first screw, then pass straight through the second, third, and fourth screws. After passing through the fourth screw, cross the two aluminum wires back to the original side and pass through the last screw. 

  7. Tighten the screws: Use a screwdriver to tighten the screws on the wood, so the washers press down on the wires beneath them and secure the aluminum wire to the wood. (make sure the aluminum wire is fixed well)

  8. Tape where the wires meet: Tape the two points on the board where the aluminum wires meet to prevent them from touching each other.

  9. Solder the matching transformer to the crossover point: Place the matching transformer in the middle of the antenna and bend the ends outward, so they touch the wires of the phase rod. With your soldering iron heated up, solder the end of the matching transformer.

  10. Connect the coaxial cable and the matching transformer: Connect the end of the coaxial cable to the port on the matching transformer and the other end of the coaxial cable to the port on the back of the TV.

  11. Place the antenna: Place the finished antenna vertically to get the best signal. Turn on your TV and move the antenna around the room until you see a clear picture on the TV.

According to the above 11 steps, you will make an antenna that can search for high-definition signals. This process is indeed very complicated and requires more materials. But when you use it to see high-definition programs, you will feel that everything is worth it.

Conclusion

After reading the above two methods of making antennas, you can try to DIY an antenna anytime. Whichever procedure you choose, you will have lots of fun and might really improve your television signals.

Compared to paying a monthly TV subscription fee or buying an expensive antenna, a homemade antenna requires only a few simple materials. Making a TV antenna yourself is a great way to save cash and improve your manual dexterity.
