**MathMate**, Sunday, June 24, 2012 at 7:07amThe height of any object viewed from a horizontal distance d and angle of elevation θ is d*tan(θ).

Let's say the top of the roof viewed from the ground 50 ft away is 30°.

The height of the roof is therefore

H=50tan(30°)=28.9 feet.

Use the same formula to get the height from the ground of the top and bottom of the antenna. The height of the antenna is therefore the difference between the two heights from the ground.
