How to build a shortwave antenna and what type to build?

I am looking to build a shortwave antenna and I felt like putting a seperate question from my other shortwave question about building one.

It obviously would be pretty cheap to make as many people say. I would definitely use a 12 or 14 gauge wire, probably copper. Now there are many different types of antenna I could build, I have heard most of the dipole antenna, other people just talk about throwing a random wire out the window, I have also heard of slinky antennas.

Now I would most likely make an outside antenna because my radio would be near a window and I think an outdoor antenna would pick up signals a lot better.

So if you could give me some pointers and such. And if you could send me steps on how to build one and such, preferably with pictures to help me out a bit. Thank you.

Here is a good place to go for Shortwave antenna help. They have all kind of forums and discussion on radios and antenna’s
