You don't notice them sort of like not noticing the galactic super cluster we are in. 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: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4487279/#__sec8title Almost what Tesla was trying to build.
