Don't forget that you'll likely need a resonating capacitor to be placed 
directly across the loopstick. Every WWVB RX unit I've seen has this, 
although there may be other schemes nowadays that don't use it.

If you are hand-winding your own antenna, you can adjust the number of 
turns to make it resonate with a particular capacitance. The rather 
large fixed capacitor will dominate, but you may want to include the 
effects of the wiring or cable capacitance if the antenna is fairly 
remote from the RX input.
