Look at it again. No base.
243Ft focal height. 44 mile visibility.
I just want to see a photo or video of what that looks like at night.
The BASE specifically means the FOUNDATION....
Buildings DO NOT STAND without a Foundation or "BASE"....
There is a Picture of it, on top of a small hill or knoll...
The picture shows the Waterline...
From the height of the Tower, you can estimate the height of the Knoll....
It is about Half of the height of the Tower....
And I'm highly unimpressed with the Fact that you are FUNCTIONALLY ILLITERATE...

He's not illiterate, he's a troll. Stop feeding it.
Ok.....
All the examples show the focal length height.
There are many lighthouses without a base.
WOW!!!
You really don't understand what you've read, do you??
Thanks for proving to all of us, that you're not really educated in the use of Math, and that you are only good at repeating things that you don't clearly comprehend...
Focal Length and Flying Height are Two Separate Mathematical equations, and you don't understand either one of them...
It does NOT include the LAND that the Tower sits upon.....
You have to ADD that part in LATER....
The Whole Tower, and ONLY the Tower, is 293 feet tall, Bottom to top of ONLY the FUCKING TOWER!!! You FOOL!!!
The knoll it sits on is ANOTHER ADDED height.... YOU MORONIC REPEATER!!!!
I estimate, from the Picture Link I posted, that the ADDED Height is about 150 Feet....
Stop with the stupid shit.... You keep using the right WORDS, but then you STUPIDLY throw in your own definitions....
