Anybody else wonder about the GPS shielding just sitting there without being grounded? Electronics is not like ordinary defensive mechanisms. When you stick a material between two places, to shield against electrical interference, AFAIK the material should be grounded.
I see 3DR is trying to sell a "GPS Shield V2". Still appears to be ungrounded. The advertising says "an emir absorbing Polymer shield". I suppose they meant "EMI" but they still appear to be making the same mistake of thinking that a physical property of absorbing something will be effective in protecting against electrical interference. Even if physical absorption were a good analogy, eventually the absorbed interference must go elsewhere.
Patent US6652777 - Method and apparatus for EMI shielding
Method and apparatus for EMI shielding
"Failure to ground the gasket adequately could result in radiation of an electromagnetic field from a side of the gasket opposite the primary EMI field."
Disclaimer: I am not knocking the Solo, I just ordered one.
