Because I seem only to reach 250 meters from my gateway, I want to upgrade the antenna on my gateway.
I am going to connect a RAK Glass Fiber Antenna with 6dBi peak gain, N-Type iPEX Connector, support 868MHz to my RAK2245 board.
If I understand correctly because I have a +dBi + gain I must configure the RAK gateway to have lower transmission power.
Anyone can tell me what to modify in the RAK gateway config?
Is there also a good way to verify if the transmitted power is not exceeding the legal limit easily?
