If you want to transmit or receive a VHF or UHF signal, you can make one on your own that can operate on a 1.2 GHz frequency. This antenna can be constructed using a Yagi design. This is a kind of antenna with three elements that sit on top of the antenna rod and connect to the spine of the antenna.

Instructions

  1. 1

    Cut three pieces of your copper wiring so that they match the lengths of your 2-by-4 pieces of wood.

  2. 2

    Use your saw to cut a shallow groove down the entire length of each of the three 2-by-4s. The groove needs to be no deeper than the size of the wire.

  3. 3

    Glue the three pieces of copper wire into the matching lengths of 2-by-4. Wait for the glue to dry.

  4. 4

    Place your 160cm length of 2-by-4 over the centre of the 2-by-2 so that the two pieces make a cross.

  5. 5

    Drill a hole through the centre of the 2-by-4 into the 2-by-2 and use a screw or bolt to secure the two pieces of wood together.

  6. 6

    Place the two remaining 2-by-4s on either end of the 2-by-2 and centre them.

  7. 7

    Drill holes through the 2-by-4s into the 2-by-2 and secure the pieces together.

  8. 8

    Drill a hole in the centre of the 2-by-2, near the centre 2-by-4.

  9. 9

    Insert a rod into the hole, which will act as your antenna mast.
