The NOAA satellites are very strong. You may not need an LNA at all. But if you were to need one, the bias tee you selected will do just the trick to supply DC power into the coax feeder up to the antenna. The bias tee also blocks DC from going into your RTL-SDR.
The FM bandstop filter is only necessary if you are near an adjacent FM transmitter that is overloading your front end. You could also be near a a cell tower, etc. that causes similar front-end overloading, etc. This bandstop filter passes DC through so that you can run an LNA in front of it.
The HAM Radio RTL SDR LNA does not have a bias tee on-board, so you would need a second one to tap DC from the feeder coax at the antenna and block DC from going to the antenna for it could actually have a DC short (Eg. a gamma match or loop antenna, etc. The LNA can be very useful for low-signal reception.
If you find an LNA with a SAW filter, the FM bandstop won’t be necessary. The SAW is a very narrow bandpass filter that blocks everything on both sides.
I really like Adam, 9A4QV’s videos. This is a passive filter, which won’t need power from the bias tee, but your LNA will.
Remember, these are all remedies to fix things. Try it without. Then solve the situation as needed.
