Spectracom 8206A WWVB Antenna 2
Antenna is designed to receive the WWVB time and frequency signal from the National Institute of Standards and Technology (NIST) in Ft Collins, CO.
Simple set up... just aim the antenna toward Colorado using the arrow. Works great indoors in Upstate NY. Not need to mount it outside (it is weatherproof). Will accept long cable runs without a preamp due to the 60 kHz frequency.
WARNING: Spectracom receivers extract the carrier from WWVB using a PLL to discipline a local oscillator. The new phase modulation scheme, to be activated by NIST in July, 2012, does not allow carrier extraction in this manner... and impacts the ability to decode time-of-day reliably.
Translation: Netclock/2 (and other Spectracom WWVB receivers) will fail. It will unlock from "time sync" and begin freewheeling when the change is initiated. The good news: cheap consumer clocks will work better.
