Question B-007-007-010

Excluding enhanced propagation modes, what is the approximate range of normal VHF tropospheric propagation?

Correct Answer

800 km (500 miles)

Explanation

While normal line-of-sight might be 50-100 km, tropospheric bending and slight enhancements can often extend reliable VHF range out to several hundred km. 800km (500 miles) represents the upper end of consistent tropo scatter/bending, before considering strong ducting.
