Hi Peter,

Unbelivable! I just found the INA111 also at RS components and even Reichelt in Germany has it available!

Now i consider to try a similar design. I'm still not sure if i'm loosing some dB here on the LF grabber since i have to use the lightning earth system here 35m above ground level. No separate clean earth available in that height. Maybe a better solution than a simple common mode choke...
Do you have further useful ideas for constructors?

Where do you have the INA111 from?

>From Farnell, the TLE2426 voltage splitter too.
