Which frequency range is most dependable for short-range tactical communications?

The Ultra High Frequency (UHF) range is the most dependable for short-range tactical communications primarily due to its optimal propagation characteristics and effective penetration of obstacles. UHF frequencies, which range from 300 MHz to 3 GHz, are particularly suited for urban environments and are resilient in scenarios where line-of-sight communication may be disrupted, such as in heavily wooded or built-up areas.

UHF signals can reflect off buildings and other structures, thereby improving communication reliability in tactical situations. Additionally, many military and tactical communication systems are designed to operate within the UHF range, ensuring compatibility and interoperability among different units. These attributes make UHF an optimal choice for real-time communication and coordination in fast-paced, dynamic environments typical of tactical operations.
