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.
