Does this heat sink negatively affect WiFi connectivity? Bluetooth?

To be fair, metal will affect a little bit of wifi or Bluetooth signals. (If it's ABS plastic, does it also affect signal strength?) But it depends on distance of the raspberry pie and the router. In addition, the metal casing is open and its surroundings are not enclosed, so we think that its effect on wifi or Bluetooth signals is negligible.
