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.
Optional: Wireless Transmission Considerations
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.
