There's a huge antenna in Colorado, I think managed by the Denver Air Route Traffic Control Center which is located in Longmont, that's used as a backup for transatlantic flights communications.

"Huge" is probably not that big vs VLF. Maybe on the order of ~50m width (~3MHz / ~100m wavelength for ~50m half-wave antennas). VLF is more like wires across entire valleys - kilometres.
