edit: It looks like NASA is back selling Radio JOVE kits again. So this might be your only turnkey choice. It uses 2x large wire dipoles for 20.1 MHz for receiving Jupiter/Io radio bursts which you just view in a spectrogram on a computers (includes SDR receiver): https://radiojove.gsfc.nasa.gov/kits/ I think the SETI "Horn of Plenty" design is a pretty good way to get started with kids. The antenna itself uses metalized foam board with copper (or even aluminum tape) to make a pyramidal horn. Making the waveguide out of folded aluminum siding is a bit more kid dangerous (tin snips cutting…

It would, but a pilot program of (much smaller/cheaper (no gpus for imaging)) STARE2 deployments around the world for fast transient radio burst detection would probably be a better start. https://www.caltech.edu/about/news/magnificent-burst-within-... https://arxiv.org/abs/2001.05077 >"When I saw the data, I was basically paralyzed," says Christopher Bochenek (MS '18), lead author of a new Nature study on the STARE2 results, ... "At the radio frequencies we observe with STARE2, the signal was much stronger than what CHIME reported. We had caught the FRB head-on."

1. Small apertures' one advantage is their being able to see a large amount of the sky at once. For any coherent aperture the larger it's span in a direction the smaller the beam pattern is in the perpendicular direction upon the sky. The bigger your collector the smaller your beamwidth the less you can see at once. Big dishes have small FOV and aren't good for monitoring the entire sky. There are ways of getting around this: physically scanning the big antenna, multi-apertures for receive across the focal plane, or by abandoning actual imaging and measuring the correlations between arrays of…
