What is the maximum range for the High power setting on SINCGARS?

• A. 5-10 kilometers
• B. 10-40 kilometers
• C. 0-25+ miles
• D. 200-400 meters

Answer: (B)

Pushing the transmitter to high power increases how far your signal can travel, but that range still depends on line of sight, terrain, and antenna height. For SINCGARS, when you’re using the high power setting under favorable conditions with a clear line of sight, the practical maximum range is about 10 to 40 kilometers. That captures the typical upper bound you’d expect in open, unobstructed terrain, while acknowledging that real-world factors can shrink it. Other ranges don’t fit as the best answer because 5-10 kilometers is more representative of low-power performance, not the high-power max; 200-400 meters is far too short for a high-power military FM radio; and 0-25+ miles is imprecise and can be misleading, since the standard range reference is usually given in kilometers for SINCGARS.
