Resistance:  

 

Obstacles such as walls, floors, windows, stucco, concrete and large metal objects can reduce the 

range.  

 

When considering the distance between the remote sensor and the atomic clock (330 feet open air), cut 

that distance in half for each wall, window, tree, bush or other obstruction in the signal path.   

 

Closer is better. 

 

Windows reflect the RF (radio frequency) signal.  

 

Metal absorbs the signal and reduces the range. 

 

Stucco has a metal mesh that absorbs the signal. 

 

Do not mount the remote sensor on a metal fence. This significantly reduces the effective range. 

 

Interference:  

 

Consider items in the signal path between the remote sensor and the atomic clock.  

 

Sometimes a simple relocation of the remote sensor or the atomic clock will correct the interference. 

 

Windows can reflect the radio signal.  

 

Metal will absorb the RF (radio frequency) signal. 

 

Stucco has a metal mesh that absorbs signal. 

 

Avoid transmitting antennas: (ham radios, emergency dispatch centers, airports, military bases, etc.) 

 

Electrical wires (utilities, cable, etc.) 

 

Vegetation is full of moisture and reduces signal. 

 

It is difficult for RF (radio frequency) signal to travel through a hill.

Moon Phase 

 

The moon phase is based on the lunar calendar and the year, month and date set. Most Internet moon 

phase calculations are based on the lunar calendar.

  

 

 

Waxing indicates growing or expanding illumination and happens after a new moon. 

 

Waning indicates decreasing illumination and occurs after a full moon. 

 

Crescent refers to the moon being less than half illuminated. Crescents can be waning or waxing. 

 

Gibbous describes a moon phase when more than half is illuminated. Gibbous can be waxing or 

waning. 

 

New Moon occurs when the moon is between the earth and sun, so the illuminated portion of the 

moon is on the back side facing the sun and we cannot see it. After a new moon, the illuminated portion 

will increase or wax until the full moon occurs. 

 

Full Moon occurs when the earth, moon and sun are in approximate alignment, with the moon and the 

sun on opposite sides of the earth. The illuminated portion of the moon faces the earth, giving us
