There are rare cases where the Uputronics filter can get overloaded, but you probably would know if you have that kind of noise. So you will likely be better off not using three filters, or even two, e.g. Pro Plus stick (has a filter) → Uputronics LNA+Filter + Dark Blue FA filter. The FA add-on filter probably gives a couple db of insertion loss, so avoid it with the Uputronics if you can. Even then you still will have two filters when you might get the best performance with one! e.g. consider an orange FA Pro stick (no filter) + Uputronics.
For gain settings, the Uputronics adds about 13db of gain over USB and 4.5/5V bias tee from my experience. So as suggested earlier by someone, you need to decrease your gain. e.g. if gain in dump1090-fa was 48, you’d probably want to decrease it to around 33.8 once you add the Uputronics and test different gain settings from there. And many stations get even better performance by lowering gain another 5 to 10db from there.
