Remote antenna for 60 kHz (WWVB) reception

Posted on Feb 5, 2014

Inside the outdoor box to which the loop is mounted showing the amplifier circuitry. The four capacitors visible at the lower-left corner of the perfboard are used to broadly resonate the receive loop. In the office building in which he worked (a city government building near downtown Salt Lake City) there was a conference room with a pair

of "Atomic Clock" receivers on a middle floor. Being that this was a modern building of steel and reinforced concrete construction, and because it was full of electronic devices such as computers, fluorescent lights, etc. neither of these receivers ever managed to get a good enough signal to synchronize themselves to the 60 kHz time signal being transmitted from Fort Collins, Colorado by the NIST station, WWVB even though the signal from that station here in the Salt Lake area is quite strong. The solution was to bring a signal into the room from outside, a project that would involve a receive antenna placed in a location that did have a good signal - such as the roof of the building - and then convey it to the conference room and somehow couple it to the clocks in question.
