The higher the dBi of the antenna, the higher the gain, but less of a broad field pattern, meaning that the
signal strength will go further but in a narrower direction, for better performance, please select proper dbi
according to your surrounding location.
Lower dBi is great for urban area, or high hotspot density areas.
And higher dBi is great for long range in suburban area or high area without obstacles.
