KFI: Building the "top hat" for new tower.

Here is the construction of the "top hat" for the new KFI tower. This replaced the tower which fell after a plane hit it in 2004.

View attachment 10801

The station was unable to get approval for a tower as tall as the "old" one, so they used this crown on the top to increase the electrical height. This is one way to "top load" a tower, the most common one being to use the top guy wires as radiators for part of their length.

Here is a very thorough analysis of the incident from AOPA:

Collision with tower severs wing, kills two

It’s critical that we understand the environment in which we’ll be flying—especially in the airport vicinity, where the aircraft is low and the distractions are many.
