What is the Manpack High power range?

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

Answer: (A)

The main idea is understanding how far a manpack radio can reliably reach when it’s set to its high-power setting. Range for these radios is largely determined by transmission power, antenna height and gain, frequency band, and the terrain between transmitters and receivers. In typical open terrain and line-of-sight conditions, a manpack operating at high power will reliably cover about 5 to 10 kilometers. That range reflects practical limits: the signal weakens with distance and obstacles, so once you push past that window, reliable communication becomes less certain unless you add help like better antennas, repeaters, or more favorable propagation, which isn’t assumed in the standard high-power case. The other ranges would require conditions or configurations beyond what a standard high-power manpack is designed to deliver—very short ranges like a few hundred meters miss the purpose of field radios, and far longer ranges generally depend on different equipment or setups not typical for a single manpack.
