LNA Installation Question

I recently got my hands on my first LNA. The spec website identifies the two connectors as “N Male (Input) / SMA Female (Output + DC)”. Which end goes towards the SDR, and which end goes towards the antenna?

On my Noeelec LaNA, the “Input” goes towards the antenna. If you happen to have the same model, when it is working, the LED will light up.


From the LNA’s perspective, input is from the antenna and output is towards the SDR [from where the LNA picks up the DC voltage to energize]
