I have found this on the net

if ur neighbor got open AP, u should try to make this dish antenna,

to gain more signal

These pictures will become my presenter,

from wiki

A Yagi-Uda Antenna, commonly known simply as a Yagi antenna or Yagi, is a directional antenna system^[1] consisting of an array of a dipole and additional closely coupled parasitic elements (usually a reflector and one or more directors). The dipole in the array is driven, and another element, 5% longer, operates as a reflector. Other shorter parasitic elements are typically added in front of the dipole as directors. This arrangement gives the antenna directionality that a single dipole lacks. Yagis are directional along the axis perpendicular to the dipole in the plane of the elements, from the reflector through the driven element and out via the director(s). If one holds out one’s arms to form a dipole and has the reflector behind oneself, one would receive signals with maximum gain from in front of oneself.

Directional antennas, such as the Yagi-Uda, are also commonly referred to as beam antennas^[2] or high-gain antennas (particularly for transmitting).

1. the motor – it swing the element of the yagi antenna ( round and round ).

2. the slider – it become a roller blade for the element ( up and down ).

3. the railway – it become a highway for the slider.
