    Subject: [NavList] Faraday cage

    The suggestion of shielding a GPS in a Faraday cage comes up here frequently. So I would like to tap into the knowledge of our shielding experts.

    I have an electronic dog fence all around the property to prevent the dog from leaving it. (The kind that emits a radio signal for a receiver on the dog's collar). But I would like to leave a section open to enable the dog to pass through it. So I tried to shield 12 feet of wire with steel pipe and grounded it.That has absolutely NO effect. Zero. Why?.
