In which band does the TACAN system operate?

Explanation:
TACAN operates in the UHF band. This military navigation system provides both bearing (azimuth) and distance, using interrogations and transponder replies on UHF frequencies. The shorter wavelengths of UHF allow for compact, practical antennas on aircraft and ground stations while delivering precise range information and reliable bearing data when line-of-sight is available. In contrast, VHF is associated with VOR/DME navigation, SHF is used for radar and high-frequency microwave tasks, and LF falls well outside the needs of TACAN’s direct bearing/ranging function. So the best fit for TACAN’s frequency use is the UHF band.
