This is an antenna that me and my collaborator, Sharath Chandra built with bamboo sticks, cable ties and normal TV cable (copper) for receiving images from the NASA NOAA satellite.
We installed this antenna in a 5th floor building terrace trying to get a space with not too many buildings around that could interrupt acquiring the signal.
Using NASA proprietary software we could anticipate the exact time when the satellite will pass over us, and be ready to get the signal coming directly from the antenna to the computer!
We had to wait for each cycle of a satellite passing, and after that we could decode the signal (indeed a sound) into actual imagery.
We put together an installation featuring the images collected with the antenna and teaching people how to build one!
This is one of the use cases for the antenna and the ecosystem that would be required around the technology for generating a benefits in a community, regarding disaster preparedness.
