  1. OLD TECH! Ancient stuff…. TODAY, you are not going to find an antenna connection on the transmitting device, and if you do, you are gaoing to need some seriously expensive feed line to connect the SMA connector on the WiFi card to the N connector on the antenna. These used to be popular in the very early days of WiFi for an activity called “war driving”. War driving was when you loaded up the car with a laptop, wifi card, Pringles can antenna, and drove through the industrial complexes looking for open networks to attack or steal bandwidth. ACTUALLY, you would be better off mounting a smartphone on an old DirecTV dish and use the smartphone as a hotspot.
