Locating the ISS and Anemometer

17

Optional: Anemometer Cable Length Considerations
• All Vantage Pro2 stations 

include a 40' (12 m) cable to go 
between the ISS and the 
anemometer. This can be 
extended up to 540' (165 m) 
using optional extension cables 
purchased from Davis 
Instruments. 

• If most of the anemometer cable 

length is unused, the coiled cable 
length can be stowed once the 
anemometer and ISS have been 
installed on a site. Attaching the 
anemometer cable to the 
mounting pole using the supplied 
cable tie is the recommended 
option.
Keep the anemometer cable 
coiled if possible during the ISS 
and anemometer assembly so that it is easily stowed once installation is complete.

• The Cabled Vantage Pro2 includes a 100' (30 m) cable to go between the console and 

the ISS. This can be extended up to 1000' (300 m) using optional cables.

The range of the radio transmission depends on several factors. Try to position the 
transmitter and the receiver as close as possible for best results.

Typical maximum ranges include:
• Line of sight: 1000' (300 m).
• Under most conditions: 200 - 400' (60 - 120 m).

Other range and transmission considerations include:
• Range may be reduced by walls, ceilings, trees, foliage, a metal roof or other large 

metal structures or objects such as aluminum siding, metal ducts, and metal 
appliances, such as refrigerators, televisions, heaters, or air conditioners.

• Frequency interferers also reduce transmission distance. Cordless phones (900 Mhz) 

are a common example of frequency interference.

• Transmission between wireless units may be obscured by something unidentifiable, or 

by some obstacle that can’t be worked around. 

• For best results, orient the ISS antenna and the console antenna so that the orientation 

and angles of the antennas are parallel to each other.
