In what frequency band do TACAN systems operate?

TACAN (Tactical Air Navigation) systems operate in the UHF (Ultra High Frequency) band, specifically within the frequency range of 960 to 1215 MHz. This frequency range is advantageous for tactical navigation as it allows for the precise determination of an aircraft's position relative to a ground-based station. The UHF band is utilized because it offers good propagation characteristics and enables greater accuracy and reliability for short-range navigation, which is essential for military operations.

In contrast, VHF (Very High Frequency), LF (Low Frequency), and HF (High Frequency) bands serve different purposes and have distinct characteristics that make them less suitable for the specific functionalities provided by TACAN systems, such as the high-resolution distance measuring and bearing information required for aircraft navigation.
