How do you shield a radio receiver from electromagnetic disturbances on the antenna?

What frequences we're talking about?

Mili-Hertz to micro-Hertz.

That's where almost all the energy is. AFAIK, it doesn't start to become a problem because current antenna have an incredibly low sensitivity on that range. But well, I can easily overlook some detail.

For the purposes of this discussion, lets say “the same frequencies the radio operates on”
