Hi everyone, I have an unusual question: Do any of you have any ideas on a DIY method for improving mobile phone reception? (my phone does not have an external antenna/antenna connector) I figured that asking physicist would be the best way of getting reliable information! I know that making a parabolic dish from tin foil can help with wifi connections, could something similar help with a phone? -Also as a side curiosity: whilst a friend was having building work done a part of her house was covered in scaffolding, for the period that the metal was in place the reception inside the house was consistently higher. Does anyone know how that might have happened? Thanks.
