* antenna connector must be SMA for 3G/LTE and RP-SMA for Wi-Fi | * antenna connector must be SMA for 3G/LTE and RP-SMA for Wi-Fi | ||
* LTE antenna's gain after cable damping must be less than or equal to 2.5 dBi | * LTE antenna's gain after cable damping must be less than or equal to 2.5 dBi | ||

When using antennas of different gain, take note that '''a higher dBi value doesn't always mean universally better coverage'''. Antennas with a higher gain value (e.g., 7 dBi, 9 dBi) tend to provide better coverage for distant devices, but antennas with lower gain (e.g., 2 dBi, 5 dBi) tend to provide better coverage for devices in close range. A visual representation of this is provided below: | When using antennas of different gain, take note that '''a higher dBi value doesn't always mean universally better coverage'''.
