TACAN uses which frequencies?

• A. VHF frequencies
• B. UHF frequencies
• C. SHF frequencies
• D. EHF frequencies

Answer: (B)

TACAN operates in the ultra high frequency (UHF) range. Specifically, its transmissions use frequencies around 960 to 1215 MHz, chosen to support the military’s distance-measuring and bearing services. When TACAN is paired with a VOR to form a VORTAC, the VOR provides bearing on VHF, while the TACAN/DME portion gives distance on UHF. The other bands—VHF, SHF, and EHF—serve different systems (VOR/ILS on VHF; SHF/EHF for higher‑frequency radar and satellite links) and aren’t used by TACAN.
