Which frequency range is commonly used for tactical communications?

The VHF/UHF frequency range is typically favored for tactical communications due to its effective propagation characteristics and suitability for line-of-sight communications. This range allows for clear voice communications and data transmission over short to medium distances, which is critical during tactical operations where mobility and reliability are paramount.

VHF (Very High Frequency) operates typically between 30 MHz to 300 MHz, while UHF (Ultra High Frequency) spans from 300 MHz to 3 GHz. These frequencies are capable of supporting various communication modes, such as FM and digital modes, which enhance the robustness of tactical communication systems. The line-of-sight propagation of VHF/UHF is beneficial in avoiding obstacles and providing less signal attenuation compared to lower frequencies.

In contrast, while HF (High Frequency) can cover long distances, its reliance on ionospheric propagation can introduce variability and make it less reliable for immediate tactical communications. SHF (Super High Frequency) is more commonly associated with satellite communications and less so with typical ground-based tactical operations. LF (Low Frequency) is not practical for most tactical communications due to its long-range but limited data capacity and increased susceptibility to interference. Thus, the VHF/UHF range distinctly addresses the needs of tactical communications, making it the correct
