 ## External Antenna
 In order to receive [GNSS](https://en.wikipedia.org/wiki/Satellite_navigation "Global Navigation Satellite System") signals, users will need a compatible antenna. For the best performance, we recommend an active, L1/L2/L5/L6 GNSS antenna.

 ### Antenna Bridge
 The antenna bridge on the GNSS Flex pHAT can be utilized to connect an external antenna to the SMA connector. For the connection to work, an U.FL cable needs to bridge the antenna connection from the GNSS Flex module to the GNSS Flex pHAT. Due to the space constraint, we recommend connecting the U.FL cable to the GNSS Flex pHAT before attaching the GNSS Flex module to the pHAT.

 ## USB Connector
 If the GNSS Flex module has the capability, a USB-C connector is provided on the GNSS Flex pHAT to interface with the GNSS receiver. However, depending on the software support of the GNSS receiver, users can either interface with the GNSS receiver directly from the Raspberry Pi or externally from another computer.
