When considering the distance between the outdoor sensor and the forecast station (300 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 outdoor sensor on a metal fence. This significantly reduces the effective range.
Interference:
Consider items in the signal path between the outdoor sensor and the forecast station.
Sometimes a simple relocation of the outdoor sensor or the forecast station 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.
