The radio horizon in kilometres is about \( 4.12\sqrt{h} \) for h in metres. What is it for a 100 m mast?
Answer: A
Substituting the height directly:
\[ d = 4.12\sqrt{100} = 41.2 \]
kilometres, so about 41 km. The square root means that quadrupling the height only doubles the horizon, which is a strong argument for siting on high ground rather than building a taller mast. Adding the receiving antenna's own horizon gives the total path length available for a line of sight link, which is the calculation actually needed in planning.
