Can/should this connect to the flight aware pro stick? should a nesdr smartee v2 sdr - premium rtl-sd be used in addition/in place of the pro stick?

You'll need an external bias tee to connect it to the FlightAware prostick. Our LNAs are designed to be used with SDRs that have bias tees, like our RTL-SDR Blog V3. A smartee would also work. However, if you really want improved ADS-B performance, I would strongly suggest using our Triple Filtered ADS-B LNA https://www.amazon.com/dp/B078TBG4H8, as with that you would see much better ADS-B performance when combined with a bias tee RTL-SDR or external bias tee.

I'd like to use this lna for hydrogen line detection (1420mhz) since the sawbird h+ is currently unavailable. will this work?

Theoretically yes, it will "see" a spike at 1420 mhz but you will need an SDR program and maybe a raspberry pi with a sound card.

at 6 and 5 giga herz, can we use it, with less amplification ? what will be the ampluficatin ??

No, only good to about 4.0 ghz.

Can this be connected directly to a rtl-sdr? it is currently too cold to get to the antenna to hook it up there but i do not want to mess anything up

This preamp requires +5vdc be applied through its output connector to operate the transistor inside the amp.Some SDR have 5vdc present at there input connector some don't.See if a DC voltmeter can detect a voltage to its input connector. If not a power injector will have to be bought and placed between the SDR and this preamp.A seperate +5dc power source would be needed to run the power injector and the preamp.
