To use a Wi-Fi signal on a portable device in your backyard, the Wi-Fi antenna of the wireless Wi-Fi router must also be outside. You can attach an outdoor antenna to the wireless Wi-Fi router inside of your home using a few electronic parts and some hardware tools. You will also need to waterproof the connection to the router so that it is protected from the elements, such as rain, that could interfere with the connection’s ability to transmit a signal from the Wi-Fi antenna.

Instructions

  1. 1

    Clamp the jaws of the pliers around the base of the antenna on the back or side of the wireless Wi-Fi router. Twist the pliers to loosen the connection of the antenna from the wireless Wi-Fi antenna.

  2. 2

    Unscrew the antenna from the back or side of the wireless Wi-Fi router with your fingers. Put the antenna aside.

  3. 3

    Screw the connector on one end of the coaxial cable into the back or side antenna connection on the wireless Wi-Fi router. Attach a BNC-to-Coaxial adaptor to the coaxial cable if the coaxial connector will not fit in the antenna connection. Screw the BNC connector of the BNC-to-Coaxial adaptor onto the antenna connection.

  4. 4

    Trail the coaxial cable along the baseboard of the walls until you reach the wall facing the backyard. Tack the coaxial cable to the baseboard with the staple gun.

  5. 5

    Cut a hole in the baseboard through the wall facing the backyard with the power drill. Push the coaxial cable through the hole. Apply silicon sealant around the hole on the inside and outside of the wall.

  6. 6

    Push the coaxial cable through the PVC pipe. Attach the end of the coaxial cable to the connector on the outdoor antenna.

  7. 7

    Apply silicone sealant around and on the connector. Let the silicon sealant set for an hour. Reapply the silicone sealant around and on the connector.

  8. 8

    Secure the coaxial cable to the side of the outdoor antenna with plastic clip-ties.

  9. 9

    Hammer “U” loops around the PVC pipe with the hammer to secure the PVC pipe to the ground.

Tips and warnings

  • Digging a channel in the backyard for the coaxial cable will provide the best protection.
  • Check for any utility lines that could be in your backyard before making any alterations to the ground.
