[Hackrf-dev] Shielding and distance from the PC makes a difference!

[Iluta V]

Copper shielding probably is the best. I have some extra copper, would you
suggest to make such a shield?

Wiki - RF shielding enclosures filter a range of frequencies for specific
conditions. Copper is used for radio frequency (RF) shielding
<https://en.wikipedia.org/wiki/Copper_in_architecture#Radio_frequency_shielding>
because it absorbs radio <https://en.wikipedia.org/wiki/Radio_wave>
and magnetic
waves <https://en.wikipedia.org/wiki/Magnetic_wave>. Properly designed and
constructed copper RF shielding

enclosures satisfy most RF shielding needs.
