For a single antenna located at a single site, maybe NAA at Cutler,
Maine. I've seen this at it is awesome. WWVL was pretty awesome too.

However, some of the ELF stuff is much bigger. I heard that there was
(is) one on the UP of Michigan that is underground, so who knows how
big it might be. The tree huggers kept cutting down the poles that
supported the above ground versions.

If you're talking height then it's KVLY's tower. 2063', the tallest
manmade structure on the planet
