I live right off of my university's campus:

The blue is the range that the WiFi will work in. It'd be great if I could connect to the uni's WiFi and have access to my files and such.

I'm planning to build a WiFi antenna or Wokfi like this:

using these:

First of all will this work?

Second question. If I have a desktop, laptop, Xbox, and iPhone how do get the above connection to work will all of them?

Thanks
