Hi I wonder if anyboday could help me. I have got 2 questions
1. Given that the radius of the earth is 3963 miles, How i can show/illustrate that the radio horizon can be approximated by sqrt(2*h).
Where h is height of antenna. what is acutally radio horizon
2.In text books, a formula is given to calculate line of sight d= 3.57* sqrt(h)
where d is distance between antenna and horizon.
my question is what 3.57 vaule represents in this formula
