Thanks for commenting.
I think I'll head out for a small (Relatively) drsstc, good grounding and a line filter.

Also, the faraday cage will not do anything for magnetic field shielding.
This is not correct. Assume first - for simplicity - that there are no electromagnetic sources outside of
the faraday cage and that the cage is perfectly conducting (and consisting of plates, not a mesh). From the Maxwell field theory you can see that a time-varying magnetic field could only exist outside the cage if there was also a time-varying electrical field. But due to the cage there is no time-varying electrical field and thus no time-varying magnetic field.
Of course in practice the cage is not perfectly conducting. Low-frequency magnetic fields could exist outside
of the cage. But the HF components of both the magnetic and the electrical field will not go outside the cage.
