An active antenna is a passive antenna that simply includes an on-board Low Noise Amplifier. 

A Switchable antenna brings together multiple technologies including a near perfectly balanced antenna design and an electronically selectable complementary radiation pattern multi-element. 

An internal GPS/GNSS active antenna with cable is suitable for mobile applications or other areas where internal antennas are required, or where not much space or volume is available. It is ideally affixed to the plastic housing of a device directly by double-sided adhesive , screw-mounting, or slot. 

Passive antennas are antennas that have no amplification or switch. Passive antennas may require an LNA on the receiver.
