-I've built myself a common mode choke last winter (2022) but haven't created
-this page yet. Also I haven't used it much because I haven't been very active
-this year.

 So this is basically a 140-43 toroid with 9 turns of RG174 connected to
 BNC connectors.
 
+It works very well and I have made two measurements recently.

+{{< figure src="logmag_outer.png" caption="It attenuates common mode current with more than 20dB" >}}

+I find this okay for now but I still wonder if this can be made any better
+(maybe 30dB attenuation?). Would I benefit from even more attenuation?
+
+I will probably find out on another day.
