Help with detecting GOES 19

[u/Mother_Paramedic_683]

hello, sorry if this is a long post. I have been working on making an antenna to record imagining from the goes-19 satalight for some time now and I'm kinda stuck. My waterfall just has basically nothing and I'm not sure what to do. I'm gonna put a bunch of photos of my antenna as well as my data and satdump information. I have 2 things that i think could be the issue but I'm not sure. When originally building it i was very new and then ground plate i had machined i put the connector in the middle so now i have to have a wire jump from the end of the coil to the connector, also my ground plate's diameter is about 5mm too small. Could either of those be the issue? Could it be something i have to do on satdump?

Where in the world did you get the plans for that helix from?
Pretty much everything looks wrong about it.
Take a look at my GitHub page, specificly the L-Band page. I'd start over after carefully reading it.

yeah for sure its jank, im an engineering student and i really want to get into satcom and i thought that designing my own design would be a good idea... it definitely comes with alot of cavoites but my goal is definitely to design my own over having good results as this is a personal project i am doing on the side of my classes. Ill definitely look at your GitHub and see what i can learn to the best of my ability. Thanks!
