A Wi-Fi antenna must gather in a wireless signal from the Wi-Fi transmitter that is connected to the internet. You can build a Wi-Fi booster that will enhance the capabilities of the Wi-Fi transmitter’s antenna in all directions--making for a stronger signal for any device with a Wi-Fi receiver to pick up. A satellite dish, a few tools and items from a hardware store are all you need. The omnidirectional antenna you will make does not violate any warranties on the Wi-Fi transmitter or on any of the devices that will be picking up the Wi-Fi signal.

Instructions

  1. 1

    Take the satellite dish over to the Wi-Fi transmitter.

  2. 2

    Place the tip of the Wi-Fi transmitter’s antenna against the back of the satellite dish at its centre. Draw around the tip of the Wi-Fi transmitter’s antenna with the black marker. Remove the Wi-Fi transmitter’s antenna from the satellite dish.

  3. 3

    Put a sheet of newspaper on a table. Put the satellite dish face down on the sheet of newspaper.

  4. 4

    Select a drill bit that as closely matches the size of the hole as possible. Unlock the power drill’s drill holder. Put the drill bit into the power drill. Lock the power drill’s drill holder.

  5. 5

    Drill a hole through the satellite dish at the point where the marker was used.

  6. 6

    Take the satellite dish over to the Wi-Fi transmitter.

  7. 7

    Push the tip of the Wi-Fi transmitter’s antenna through the hole in the back of the satellite dish.

  8. 8

    Wrap duct tape around the antenna where the wire meets the hole to secure it in place. Turn the satellite dish over.

Tips and warnings

  • You can permanently attach the antenna from the Wi-Fi transmitter to the dish using bonding glue.
  • Adult supervision is necessary if the person making the omnidirectional antenna is underage since a power tool is being used.
