+### LNA Gain
+
+Set LNA Gain for better RX sensitivity, by default AGC (Automatic Gain Control) is used and LNA gain is not used.
+
+```arduino
+LoRa.setGain(gain);
+```
+
+ * `gain` - LNA gain
+
+Supported values are between `0` and `6`. If gain is 0, AGC will be enabled and LNA gain will not be used. Else if gain is from 1 to 6, AGC will be disabled and LNA gain will be used.
