WWVB ANTENNA
The WWVB antenna receives a radio signal broadcast at 60 kHz from two transmitters near Fort Collins
in Colorado. One benefit of using the WWVB signal is that as they have two transmitters that have
different scheduled down times, the WWVB signal is not affected by maintenance.
One thing to bear in mind with a radio-based antenna is that certain electrical equipment generates noise
on the same frequency as the radio signal and can cause interference. Some things to avoid are older
computer monitors, switch mode power supplies and air conditioning units.
For more information on the WWVB signal please refer to the National Institute of Standards and
Technology (NIST) under the Time and Frequency Division at www.nist.gov/pml/div688/grp40/wwvb.cfm
