Scenario:
I've set up two wifi hot spots outside of my house at distance lesser than 20 meters as i don't get any ISP signal inside my house. But the problem is now i get very weak signal in my house because of nature of walls. I'm afraid of buying any repeaters as they reduce the speed by two.
My Idea:
So i've thought of building two simple omni-directional WiFi antennas myself (such as biquad or helical) and connect them to each other by a cable, and put one at outdoor and other at indoor. But i'm not sure if this would work out, so i need your suggestions please..
Additional Infromation: I got this idea from following instructable, but it is not for WiFi, and not simple as i think http://www.instructables.com/id/DIY-2G3G4G-Wireless-Cell-Phone-Signal-Booster/
