To make a decent link, you need directional aerials at both ends ideally. A big aerial at one end is OK, but it will pick up so many signals that trying to pick out the one you want becomes difficult for the electronics. The WiFi frequency range is so congested that only by boosting somehow the signal you want to receive (and don't forget you are sending and receiving all the times with WiFi) that you can get a strong link. You will receive all the signals within a given radius - sitting here in my lounge I can see over 15 routers, some up to 400M away, but I would struggle to connect with any reliability to the more distant ones that are on the same channel as nearer ones.
