This is just a cheap solid aluminum connector designed as an antenna NOT a flexible cover with an internal copper antenna as shown in the pictures. This means it's no better than many other cheaper options. UPDATE: The seller says it's copper inside, which it actually isn't, and is just covered in aluminum. You shouldn't design antennas in this case, since almost no RF signal would ever reach a hypothetical internal copper antenna - didn't you study wave theory in engineering school?
