NOTE: This cradle works on the inductive/passive principle, same as a number of car kits, where the signal travels from the antenna along the lead into the back of the cradle, it is then transmitted passively into the phone.

Therefore, please be aware depending on your set-up and situation you might see little improvement. This is not the fault of the cradle, it can only pass on what it receives. If you are witnessing only a slight signal gain you should think about upgrading your antenna, or confirm that it is of the correct frequency for your phone\'s network which is the most common mistake, using an existing antenna on a car for example.
Frequencies: (For Australia):
Next-G: 850MHz.
GSM (2G): 900/1800MHz.
3G: 2100MHz.
