How To aim antenna to get the channels i want?

[kissyy]

Hi Guys please I need help
I finally decided to cut the cable, but i still wanna watch the news and my favorite so i googled and found one homemade antenna so I made one of the indoor coat hanger hdtv antenna following one of the videos on youtube.I've tried and it worked , at least I could get 2 digital channels and one analog.The thing is I dunno what to do to get CBS and Fox .One digital I can get right now is nbc, which is one of the channels I want too .It is working pretty good, but i dunno how to aim the antenna to get all the channels I mentioned .
Another thing i should mention is that I live on a second floor, which it might make a difference i dunno.
Can somebody take a look at the reference bellow and tell me what do?
