WebApr 8, 2024 · Remember that increasing by 3dB doubles the signal strength, but a 6dB increase is required to double the range. Thus, upgrading from a 200mW to a 400mW VTX will not double your range but rather increase it by 50%. It’s essential to note that simply increasing output power will eventually result in diminishing range returns.
