## Questions & Answers

**Q: Is this an inner/outer dc block? in other words, does it block dc through the center conductor and the through the outer shield?**
A: There is no way for it to block power through the outer shield as there is no insulator on the exterior metal. 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.  Thanks
