your antenna system is 50 ohms, meaning you would not want to use 75 ohm coax because it would introduce a mismatch, causing signal loss.

By stacking gains I mean every small thing you do adds up. For example, you could get a higher gain antenna such as a 4-element yagi, lower loss coax, and those two improvements would combine.

The filter/amp designs are basic conceptual models. They will work, but could have the effect of increasing noise more than they increase signal. component selection is very important
