My installation is the orange FA stick, “old” FA filter, then a short piece of flat coax cable, some 10-15 meters of good quality Hirschmann Koka 9TS coax cable to the rooftop where it connect to the FA antenna.

Not extremely ideal, but it has been working fine for 3+ years.
Recently though, I’ve been think of ways I can improve it.
The best thing is to move everything to the antenna (in a waterproof box) with ethernet cable going down inside powering it with POE.
Moving the RPi to the roof could work (I haven’t needed to touch it for years) but still; it’s not really accessible there…
The new FA filter (this would make perfect sense to replace the old filter.
However, people have notified me of the RTL-SDR LNA which should be placed at the antenna with something (dongle or injector) powering it.
But I’ve some options:
- If I want to change as little as possible, I could replace the old FA filter with a new one. Costs about €30.
- For a little more (basically a few euros for a bias tee injector) I could place the RTL-SDR LNA at the antenna and this should provide better results than option 1. Right?
- Instead of a (cheap) bias tee injector; I replace my orange FA dongle with one that can provide the 5V; either the RTL-SDR V3 or Nooelec *NESDR SMArTee v2.
Those are options if I don’t want to change much of the installation. Best solution their is probably the LNA at the antenna; but would replacing the orange FA stick with one of those 2 also provide better results or is that negligible?
If I would want to change more; I could move everything to the roof. So antenna -> filter/LNA -> dongle -> RPi -> ethernet with POE. My gut says this would be the most optimal solution, but I’m not exactly a fan of moving the hardware up there. But if I would do that; would the LNA make more sense than the dark blue FA filter, since I would not be using a long piece of coax anymore? The LNA is a filter just like the FA filter, but it also meant for coax losses.
And same question here about replacing the orange FA dongle with either of those other two; would that make sense then?
