I doubt that you read comments that come years after you make a video. But I will leave this in case anyone wants to try to improve on this. I think it is a really good idea and there are lots of tools and methods to improve on it. Particularly for humans, but for other things too. You might take a glance at https://en.wikipedia.org/wiki/Holmdel_Horn_Antenna and read, particularly, “Consequently, it is an ideal radio telescope for accurate measurements of low levels of weak background radiation. The antenna has a gain of about 43.3 dBi and a beamwidth of about 1.5° at 2.39 GHz and an aperture efficiency of 76%” I expect it can be 3D printed these days, small as you like. And the waveguide and circuits can all be optimized, and calibrated with real time data from many inexpensive sensors.
