Andy Lee made a post on the AVS Forum with two very good Noise Margin diagrams, one for an indoor antenna without a preamp and the other for an outdoor antenna with a preamp.

You have to log in to see the images in his post, but you should be able to recover the images from the attachments there or here.

I added some notes to his diagrams to help me understand the Noise Margin concept when I was learning about it.
