Re: GPS signals blocked by acrylic?
Research done with Lexan has shown issues with signal transmission when the angle of incidence between the transmitting antenna and the Lexan material is greater than 30° from perdendicular. Since Acrylic has similar electrical properties to Lexan (dielectric constant, dielectric strength, dissipation factor, surface resistivity....), and since GPS works by having satellites at varying angles & distances from the receiver....it would make sense that an acrylic 'lid' over the GPS receiver could cause signal problems.
Please forgive my hyperanthropomorphization.
Every answer reveals new questions.
And, yes... there's always a better way to 'do that'.
