I use this to isolate my LNA from the rest of the electronics. After nearly a year I have had no problems.

Remember, these are for SHORT TERM use. You do not use them at the top of it's rated DC power while doing TX or RX for long periods (multiple hours), They will get hot, and that will impact your signal.

I'm not seeing much signal loss with this inserted. While it was unfortunate that I didn't see the Ham It Up Nano needed a DC blocker for some RTL sticks, it does very well.Simple but effective, and not as janky as the other solution was gonna be x>x

SDR用の保護とスペアナの保護に使っています。もう少し長さが短いと使い勝手が良いのですが、長過ぎます。

It does the job! Blocked the voltage from a SAWbird+NOAA back to the SDR. Unfortunately this solution was not going to work for my installation and instead went with an SDR with bias-tee.
