The purpose of a TV antenna is to receive the signals being sent from a broadcast tower. A Yagi antenna is designed to be directional and can be aimed at the broadcast tower and receive a signal better than an antenna two or three times its size. You will need a portable antenna kit to modify and an electronic part from a hobby store to make the Yagi antenna. You will also need to mount the Yagi antenna once it is made.

    Place the Buddipole antenna pole fully into the bottom of the Buddipole tripod mount. Turn the tripod valve fully clockwise to hold the antenna pole in place.

  3. 3

    Slide the Buddipole boom pole halfway through the hole in the top of the tripod mount. Turn the tripod valve fully on the top of the tripod mount fully clockwise to hold the boom pole in place.

  4. 4

    Screw one end of a Buddipole antenna pole into the 2-inch end of one of the 2-inch IT adaptor.

  5. 5

    Screw one end of another Buddipole antenna pole into one end of the other 2-inch IT adaptor.

  6. 6

    Place the hole of the 1-inch diameter IT adaptor over the end of the Buddipole boom pole. Push the IT adaptor over the boom pole until it is stopped by the tripod valve on the top of the tripod mount.

  7. 7

    Screw the free ends of the two IT adaptors connected to the antenna poles onto the two ends of the IT adaptor.

  8. 8

    Wind the ends of the two wires connected to the VHF adaptor around the base of the two locking ring knobs.

  9. 9

    Screw the locking knobs into the holes into the front of the two 2-inch-to-1-inch diameter IT adaptors.

    Secure the base of the Buddipole antenna pole into the ground or mount it on the roof.

  11. 11

    Aim the antenna poles that are now your Yagi antenna in the direction of a broadcast tower.

  12. 12

    Screw one end of a coaxial cable into the connection on the VHF adaptor. Screw the other end of the coaxial cable into a cable box or TV’s coaxial input.

Tips and warnings

  • Having an unobstructed view between the Yagi antenna and the direction of the broadcast tower will aid in receiving a strong signal.
  • A wireless home network that is close to the Yagi antenna can cause interference issues.
