Working Gain – The current gain measured while the booster is working under different conditions. When the Input signal is
weak, the booster will work with at the max gain, but when the device detects too much strong input signal, it will automatically
reduce the gain to avoid self-oscillation of the system.
Reduced Gain – This value indicates how much the gain has been reduced according to the input signal strength.
This message means that the outdoor signal detected by the booster is not good enough.
