Figure 26: NEO-6 passive antenna design for best performance and increased immunity to jammers such as GSM
For information on increasing immunity to jammers such as GSM, see section 3.3.8.
When using an external LNA in PSM on / off mode, pin 17 can be programmed as ANTOFF.
To configure the ANTOFF function, refer to the u-blox 6 Receiver Description including Protocol
Specification [3].
Use caution when implementing ANTOFF configuration since forward compatibility is not
guaranteed
