How sensitive is the balanced probe to shielding effects (trees, houses)?

Don't know yet. But see those screenshots. There are much less
local interference lines visible.

Any difference to the E field probe?

This IS an e-field probe, but a balanced one.
Got the idea from there:

Where do you have the INA111 from?

From Farnell, the TLE2426 voltage splitter too.

What are the differences on 137 kHz? Is there a significant S/N improvement?

Not tested yet. But as I wrote it should work.
