Kinda like distracted driving. You don't notice things until you run
into them.

Anyway, 900 MHz yagi antennas are kinda pedestrian. Getting something
to work at VLF frequencies is a real challenge. Incidentally, did you
know that the original plan was for WWVB to transmit on 20KHz instead
of 60KHz? 2.2% radiation efficiency at 20KHz:

Almost what Tesla was trying to build.

Too bad WWVB doesn't have a voice announcement:
