I'm no electronics expert, but I am wondering if a "long wire" antenna
might be better than a coil for a low frequency of that sort (50' or so
)? Good luck on your project.

Most factory made radio controlled clocks use a thick ferrite antenna. I
have an Atomic Time wall clock that uses a 6-7 inch ferrite, and my Sony
bedside clock has a ferrite in a bulky enclosure attached with a wire. I
figure that he's got some electrical value wrong, like somebody else
said, but I wouldn't know what.

I"m trying to build a clock that uses the WWVB signal to keep its own
time. I have everything built and working except the Antenna portion.
I have a 1.1mH ferrite rod Antenna.
I know tuning it would require a capacitor that I calculated to be
7700pF. The problem I am having is tuning it. I am not sure how to
test it to make sure it is working correctly. I have tried
broadcasting a 60kHz signal from a function generator and viewing it on
an O-scope and Spectrum Analyzer, but I"m seeing nothing. I"m looking
for any suggestions to prove I have this tuned correctly.


Thanks
