The external antenna is only active when the phone is docked in the snap in adapter. There exist tow types of phones:
a) Older phones like Siemens or Nokia (like 6310) which have an antenna connector. Those phones are connected by "wire" directly thru the snap-in to the external antenna.
b) Newer phones (iPhone, HTC, newer Nokias...) don't have an antenna connector. They only get power, voice and remote-control thru their connection pins. To give those phones also the benefit of the external antenna the corresponding snap-in adapters have an inductive coupling. This is better than nothing but inferior to the SAP-Snap-In or those older phones snap-in adapters.
