87 feet. Factoring in the 10 foot room, this leaves a maximum of 77 feet of remaining signal range. This allowance is typically enough for a frame wall with non- metallic siding; however certain materials can reduce range even further. Metal siding, stucco, and some types of glass can reduce signal range by as much as ¾ or more, compared to the ½ reduction typical of most obstructions. It is possible to receive a signal through these materials, however maximum range will be much le

ABOUT WWVB (Radio Controlled Time) The NIST (National Institute of Standards and Technology—Time and Frequency Division) WWVB radio station is located in Ft. Collins, Colorado, and transmits the exact time and date signal continuously throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through the internal antenna in the intelligent weather station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours.
