A taller way to tell time

Liblice II, the tallest structures in the Czech Republic, are about to come down. They carried the 1.5 million-watt signal (30x the maximum power of an AM station in the US) of  Czech Radio Two until 2021 on 639 mHz. The cool thing is this (from that last link, translated):

After the removal of the Liblice masts, the Czech height record will move to the Pilsen Region. The Krašov transmitter, which measures 347.5 meters, will become the tallest structure in the country.

The Krašov transmitter in the Pilsen region has become part of the largest sundial in the Czech Republic. It casts a shadow several kilometers away. (March 20, 2018)

Since 2018, its mast has also served as a giant gnomon, a sundial indicator. A three-meter-high dial with Roman numerals has been built on the land near the transmitter.

Whoa! There are hundreds of broadcast towers around North America—some almost twice the height of these Czech ones—that could also serve as giant sundials. Has anyone thought of that? Or built one?

I nominate KXTL-TV’s 1997-foot tower in Walnut Grove, California, which I shot in 2019. (Fact: when I shot that set, one could walk right up to that thing. It’s a helluva sight.)
