Same frequency, but you wouldn't do both at the same time. See, you can't transmit AM WWVB until you first know what time it is. To get the time you enable the ES100 and listen to BPSK WWVB. So the ES100 receiver and Arduino transmitter are not active as the same time. One example might be to enable the ES100 for 3 minutes each hour and run the Arduino for the balance.

Use the standard dual right angle ES100 antenna setup to receive BPSK WWVB. For transmit, you likely don't need, and legally don't want, an antenna. The Arduino is likely within a few feet of the 24h RC clock that you're trying to set. If it doesn't work first time, dangle a jumper off the GPIO pin.

How far apart would the antennas have to be?  How would you calculate that
distance?  Or what is the right question?
