Wifi repeater

Don't have much time right now to get in depth with this. But, when I said 'antenna' I didn't really mean a big bucks roof mounted thing. If you have good wifi to your phone, on the side of your building facing where the signal is coming from, those 4 inch antennas on the home routers mounted outside would be ok. Just need a cable from that to the device inside. Low buck redneck way, punch a couple holes in the wall for power and network cable (or just through the door), set it on the ground outside. Unplug it and put it back in the garage when you go back in.
I'll have more time tomorrow.
