Diana Eng posted a tutorial over on Make: Online for making your own collapsible fabric antenna for ham radio! It rolls up for easy travels.

One of my favorite ham radio activities is making contacts on satellites. It’s really fun to know that you’re controlling something that’s receiving and sending communications from space. But communicating with satellites means carrying a big Yagi antenna around. So, I decided to use my fashion sewing skills to make a collapsible fabric Yagi antenna that’s much easier to transport.
