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 ane-
mometer. This can be extended
up to 540' (165 m) using
optional extension cables pur-
chased from Davis Instru-
ments.
• 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 anemome-
ter 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 appli-
ances, 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 unidentifi-
able, or by some obstacle that can’t be worked around.
• For best results, orient the ISS antenna and the console antenna so that the orienta-
tion and angles of the antennas are parallel to each other.
