Alex Pettit-Umbrella Antennas.

Of the many sub-hobbies tied to Amateur Radio, none can compare to the allure of deep space radio signals.

In this video from the Society of Amateur Radio Astronomers, Alex Pettit (KK4VB) shows you how to design, build, and use a "21cm Hydrogen 1 meter Umbrella Radio Telescope."

Alex describes the project step-by-step and provides a list of commonly available materials to build your own radio telescope.
