If you are interested in a Yagi antenna that doesn't need to transmit a very strong signal, you can make one on your own. A homemade Yagi antenna will be able to transmit a signal more than 10 meters, but it won't be as strong as a commercial antenna. This can be useful if you are relatively close to a cellular tower and you don't have a lot of cash to purchase an antenna with.

Cut your 2X2 length of wood down to 143cm and lay it on a sturdy work surface. This piece of wood will be the base of the antenna.
Cut one 2X4 to 162cm in length, another to 160cm in length and the remaining 2X4 to 146cm in length.
Cut a groove down the entire length of each 2X4 just deep enough for the electrical wire. Place lengths of electrical wire equal to the length of the particular 2X4 in the grooves and glue them into place.
Place the 162cm 2X4 over one end of the 2X2 and the 146cm 2X4 over the other end. Make sure they are centred over the ends of the 2X2.
Drill a hole through the 2X4s and into the 2X2s. Use screws or bolts to secure the pieces of wood together.
Place the 160cm length of 2X4 over the centre of the 2X2 and drill a hole through it and into the 2X2. Use a screw or bolt to secure the two pieces of wood.
Drill another hole in the centre of the 2X2 big enough to accommodate a metal rod and insert the rod in the hole. This will be the antenna stand.
