[wxqc] Davis Vantage Pro2 Question

[Thomas Giella KN4LF]

The anemometer will be up at 33 feet but also located approximately 100 feet in the horizontal from the ISS, so an extension cable will be necessary.

  I thought temp/humidity sensors were supposed to be about 2 meters or 5 feet above ground. It doesn't really matter where the barometer is as long as you enter the right elevation.

    I own a Davis pro 2 plus and the cable supplied is plenty long if you
    install it to NWS standards.

    1. the weather vain should be at 33 ft and they supply 40 ft.
    2. the rest of the interments should be at 3 meters above ground below the 
    weathervane.

    So you have plenty of cable supplied by Davis for an install.

      Hello To All,

      I'm new to the eGroup.

      I just purchased a Davis Vantage Pro2 with the optional fan aspirated 
    temperature/humidty shelter. As all know the Pro2 has the integrated sensor
    suite (ISS) with wind vane/anemometer attached. You can run the included
    cable of 40 feet between the ISS and anemometer/wind vane unit and add cable 
    extensions of up to 540 feet.

      For better wind data accuracy I need to detach the anemometer/wind vane
    from the ISS and place it at 35 feet up on a mast, further away than the 40
    foot included extension cable. 

      I have aquestion. Is the 40 foot extension cable a regular telephone type
    cable with male connectors on each end? In other words can I buy regular
    telephone cable extensions at Wal Mart or Home Depot to use between the ISS 
    and anemometer/wind vane? Or do I have to buy the Davis (overpriced in my
    opinion) cables?

      Next month I'm buying the model #6332 wireless version of the wind
    vane/anemometer and the cable thing will not be an issue. 

      Take Care,
