Testing Antennas For GOES Geostationary Weather Satellite

I've been trying to find a use for my ~30" parabolic dish, which is light enough to fit on an old motorized camera mount for aiming. After experimenting with a variety of center feeds, I was able to receive data from the Geostationary Operational Environmental Satellite (GOES) #16, with views of North and South America. I also played around with the big fold-up dish some more, it gets a better signal as it's much larger, but despite being "portable" it's still a little clumsy to work with.

The feed that worked best for my little dish turned out to be a miniature 3-element Yagi antenna made from wire scrap. The middle dipole is about 83mm total, the director was 66mm, and the reflector was 87mm. Each element was 22mm from the next.

As usual, I'm using an RTL-SDR Blog v3:

And a Nooelec Sawbird+GOES Filter:

I'm also using SDR++ (https://www.sdrpp.org/) and Satdump software (https://github.com/SatDump/SatDump)

Antenna SWR tuning is with a Nano-VNA V2: https://www.ebay.com/itm/353177205291
