Power is only blocked through the center connection. **Q: Does this go in between the lna and the sdr or betwen the lna and the antenna ?** A: Hi, it depends on what you are using it for! If you contact us at support.nooelec.com with details we'll be happy to help, thanks :) **Q: Is this what you use between noaa and goes lnas and the sdrs nooelec makes? is it enough to use the power plugs for the lna's?** A: Its to protect your SDR from the power an LNA uses that might feed back through the antenna connection. For that it's worked great for me. **Q: which way do I connect this?** A: Doesn't matter.
