Step 2: Prepare the coaxial cable

Now that you have gathered all the materials, it’s time to prepare the coaxial cable for your DIY TV antenna. This step involves trimming and stripping the cable to ensure optimal performance.

Using your wire cutters, carefully trim the coaxial cable to the desired length. Keep in mind that the length will depend on your specific setup and the distance between your TV and the antenna. Measure twice, cut once to avoid any unnecessary errors.

Next, take your wire strippers and remove about ¾ inch of the outer insulation from one end of the coaxial cable. Be cautious during this process to avoid damaging the inner wires. If needed, gently twist and pull to loosen the insulation before sliding it off.

Once the outer insulation is removed, you will see a braided wire shield surrounding a plastic insulator. Carefully fold back the braided wire shield and trim it away, exposing the inner plastic insulator.

Now, gently pull off the plastic insulator, revealing the copper core wire at the center. Take care not to damage the copper core wire or any of the remaining inner insulation. The copper core wire is the essential element for receiving the TV signal, so it’s crucial to keep it intact.

With the coaxial cable properly prepared, you’re now ready to move on to the next step: creating a T-shaped copper wire element for the antenna.

 

Step 3: Strip the coaxial cable

With the coaxial cable prepared, it’s time to strip it to ensure optimal signal reception for your DIY TV antenna. Stripping the cable will expose the necessary elements to create a functional antenna.

Begin by securing the prepared end of the coaxial cable firmly in one hand. Take the wire strippers and carefully strip away the outer insulation of the cable. Make sure to remove approximately ¾ inch of insulation to expose the core wires underneath.

Once the outer insulation is stripped, you’ll see a braided wire shield surrounding a plastic insulator. Very gently, fold back the braided wire shield to expose the inner plastic insulator. Take care not to damage the delicate wires inside.

After exposing the plastic insulator, check for any stray wires from the braided shield that might be touching the inner insulator. These stray wires can interfere with the antenna’s performance, so it’s essential to keep them clear.

Next, using your wire cutters or a sharp utility knife, carefully cut away the plastic insulator, exposing the copper core wire at the center. Take your time and be precise, ensuring you don’t accidentally cut the copper core or any of the remaining insulation.

Inspect the stripped end of the coaxial cable to ensure that the copper core wire is clean and undamaged. Any frayed or bent wires can negatively impact the antenna’s performance, so straighten and trim as needed.

With the coaxial cable properly stripped, you’re now ready to move on to the next step: creating a T-shaped copper wire element to complete the antenna’s construction.

 

Step 4: Create a T-shaped copper wire element

Now that you have successfully stripped the coaxial cable, it’s time to create the T-shaped copper wire element that will serve as the main receptor for your DIY TV antenna.

To begin, take your solid copper wire and measure out a length of approximately 31½ inches (80 cm). This length allows for optimal reception and signal strength. Use your tape measure to ensure accuracy.

Once you have measured the length, carefully cut the copper wire using your wire cutters or a sharp utility knife. Make sure to create a clean, straight cut to ensure the best performance.

Now, take one end of the copper wire and bend it at a right angle, forming the horizontal part of the T shape. The length of this horizontal section should be approximately 8 inches (20 cm).

Next, measure and mark a spot on the vertical section of the copper wire, approximately 2 inches (5 cm) from the bottom. This will be the point where the copper wire will be connected to the coaxial cable.

Using your wire cutters or a stripping tool, strip off approximately 1 inch (2.5 cm) of insulation from the marked spot on the vertical section of the copper wire. This will expose the bare wire for the connection.

With the T-shaped copper wire element complete, you’re now ready to move on to the next step: attaching the copper wire element to the coaxial cable.

 

Step 5: Attach the copper wire element to the coaxial cable

With the T-shaped copper wire element prepared, it’s time to attach it to the coaxial cable to complete the construction of your DIY TV antenna.

Begin by carefully inserting the stripped end of the coaxial cable into the hole that you created by stripping the insulation on the vertical section of the copper wire. Make sure the copper core wire of the coaxial cable is fully inserted, reaching the marked spot.

Once the coaxial cable is inserted, use electrical tape to firmly secure the connection. Wrap the tape tightly around the exposed copper wire and the coaxial cable, ensuring a secure and stable connection. This will prevent any movement or signal loss.

After securing the connection with tape, inspect the joint to make sure there are no loose wires or exposed conductors. Any loose connections can interfere with your antenna’s performance, so double-check everything before moving on to the next step.

With the T-shaped copper wire element successfully attached to the coaxial cable, your DIY TV antenna is starting to take shape. However, there’s one more crucial step left: connecting the coaxial cable to your TV.

 

Step 6: Attach the coaxial cable to the TV

Now that you have completed the antenna construction and attached the copper wire element to the coaxial cable, it’s time to connect the antenna to your TV. This step will allow you to start enjoying free over-the-air channels.
