Unidirectional wifi Extender

There are a bunch of ways to hack a WiFi antenna, but here’s an interesting one that uses a metal strainer. Everything that you see, you can get at a dollar store. This is very similar to the asian metal strainer hack, but looks like it’s a bit more useful if you can get it on a tripod and with a long enough USB cord. There shouldn’t be any RF loss within the USB since it’s right at the tip of the USB extension.
