Hello everyone

I’m back home, and I’ve finally figured out the cause of the antenna degradation. It turns out the cable that holds the antenna sheet on the flexible fiberglass tubes had stretched over time. This caused the dish’s diameter to shift from 2.4 to 2.6 meters, altering both the focus and curvature. As a result, during my last expedition, I lost about 3 dB in performance.
