How far away were you able to make a WIFI connection using such simple directional antenna? It is amazing if it was a few blocks away. But I wonder if the distance is far enough to be practical when trying to make a connection from a camp site. My other question is if tampering a private WIFI network nearby is OK. But I do know some people leave their home WIFI open all day and let others to make connection to the internet. They say why not share while I am not using it. I wish more people do this. It is really beneficial for people on the road.
