Notice: I made a YAGI UDA antenna with higher gain than this.

The WiFi router is located in another room away from the computer.
For that reason WiFi waves are weak.
I made a Yagi antenna to attach to the antenna of the router.
As a result, the strength of WiFi waves has almost tripled.
Note:
This adapter turns omnidirectional antenna into directional antenna.
The sensitivity increases in the directivity direction,
but the sensitivity in the other direction decreases.
