I have a Sharp atomic clock that does a great job of receiving WWVB when I place it in front of an east facing window of our house. I would prefer to place it 3 to 4 feet away along the wall that has the window, but it almost never syncs with the signal when I place it there. The clock has no provision for connecting an external antenna. Has anyone had success making any kind of passive coupler to extend reception in front of the window 3 or 4 ft away? When I’m sitting at my desk I face south and if I could place the clock 3 to 4 feet south from where it is now it would put the clock in an easier to glacé at position.

That clock is frustrating. It is receiving a very low freq. The 'antenna' in those clocks is usually an LC tank coil tuned to that freq. So it is looking at the magnetic vector for the most part. There are medical doctors who like to bring these into their offices in the middle of a big steel framed hospital, with a bunch of noisy computers running "Epic". They often don't work there. The "time" when they usually realize their clock is no longer getting updates is when daylight savings begins or ends ... as I suspect YOU just did. Move it to the window for maybe 12 hours and let it figure things out and fall back on it's own. Then return it to wherever. But from then on it's an ordinary clock with a quartz crystal time base of 32.768 KHz. It might get an update once in a while.
