I recently transplanted some guts from a radio controlled clock and stuck it in anohter clock that's in an awkward place and often gets forgotten. The ultimate goal is to stick a solar cell in the clock and just leave it to exist. Unfortunately, the clock I transplanted the guts into is all metal, so the radio controlled parts are having troubles pulling the signal. I read about passive resonant loop antennas that you could make and just stick in your attic, and field concentrator antennas that you put behind/near the clock itself to help the signal.
The clock itself has a thin wire looped and waxed around a ferrite rod. in the back of the clock module. What can I do to try and beef up the signal? How would I go about calculating and making those antennas?
What is the frequency it receives?

I believe it operates on 60kHz, since that's what WWVB transmits

Cool clock!

Just make a whip 1/4 wavelength and feed it out of the clock. You could hide it in the face

Try removing the ferrite rod and running wires out to it outside the metal case. Correct orientation in relation to the station will help.

Thing is, we have another one that faces the opposite direction, not perpendicular, and it works fine.
