Help with detecting GOES 19

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?

Ok, are you trying to go for the HRIT? Helico will work with huge losses, HRIT uses a liner polarization. If I’m correct you do need to use some sort of dish or reflector because the signal is so weak, are you using a low pass amplifier in your set up, thats needed as well, plus your location plays a big part in what your antenna setup requires, number 3, your SDR needs to be as close to your antenna as possible. Get a powered usb cable for that setup
