Shielding only prevents "E" signals from entering the ferrites. It has no effect on any magnetic fields. Many of us operate 'unshielded', because we've seen little or no difference. I've a noisy "H" environment so shielding made absolutely no difference for me. Others have required shielding for electric fields. You have to determine what your environment requires.
Shielding won't hurt, but isn't always necessary. Many of us also do not have 'ferrites' outside... many use them inside. E field probe and preamp MUST be outside, away from structures and noise, and a few meters above the earth.... and there is no shielding required, or effective.
