I am trying to setup a wireless network to a structure 300 meters away from my place of work. I am looking at getting advice on what types of wireless direction antennas I should use, Brand and Model. My setup will most likely involve a bridge connected to the main building with a direction wireless antenna on that, a direction wireless end on the structure 300 meters away and then either a router or bridge to a router. I am looking at advice on what I should buy, if the setup is ok, and anything else you might think is good. Do I need surge suppressors for example?
