Hi all,

I'm kinda new to the SDR world. I have a pretty simple question about LNA's. Does the antenna connect to the input or the output? I was look at the new nooelec Goes LNA specifically and don't want to connect the device up the wrong way around.

Thanks a lot!

All the LNAs i have including a nooelec, the input is the antenna side, output to the radio.

Yep think of the way that the signal travels. The signal is input from the antenna, gets amplified by the LNA, and then is output to the SDR. Reversing most LNA's shouldn't break it, but better not try just in case.
