I am using a Davis Vantage Pro2, with WeatherCat , and obviously, a MAC. I do not have extra sensors. Wish list is the UV and solar but....
I am up a little high from the surrounding area, and I have the station on a pole about 8 feet above the roof line. House is 391 feet and station is at 420 feet .Pictures on Wunderground. I have some trees to my east. So, always add some to any easterly wind velocities I may report.
