Attach them to a wooden rod, hanger, or PVC pipe using strong tape or zip ties.

  • Leave a small gap (about 1–2 cm) between the two can bottoms—this is where signal reception is strongest.

    • Step 3: Attach the Cable

    • Strip the end of your coaxial cable to expose the copper wire.
    • Attach the copper core to one can and the outer wire to the other using screws, solder, or tightly twisted wire.
    • Plug the other end of the cable into your TV’s antenna input.

    Step 4: Test and Adjust

    • Place your new antenna near a window or high location.
    • Rescan TV channels on your television.
    • Adjust the angle or distance between cans if needed.

    💡 Wi-Fi Signal Booster Version

    If you want to boost Wi-Fi, here’s a simplified version of the same concept.

    What to Do:

    1. Cut the top and bottom off one soda can and slice it lengthwise to create a curved sheet.
    2. Place it behind your router’s antennas or USB Wi-Fi adapter to focus the signal direction.
    3. For dual-direction boost, use two cans to reflect signal on both sides.

    This can improve coverage by up to 30%, depending on your space and obstacles.

    🎯 Pro Tips for Best Results

    • Higher placement = better reception. Place the antenna near a window or up high.
    • Keep away from electronics to reduce interference.
    • Use a signal amplifier if needed, especially for rural areas.
    • For Wi-Fi, aim the can “dish” toward your dead zone for better coverage.
