siting a Fine Offset WH1080 weather station

Hi,
I have the above weather station. I have not set it up as yet, as I was unsure of the siting of the sensors. I plan to site it on my garden shed, but should it be set quite high? I was planning on siting it on a pole about 4ft above the shed roof, mounting the rain gauge onto one of the shed barge boards, and mounting the temp sensor at the bottom of the pole, but sheltered under a shed extension. If someone could let me know how to put photos on the forum, I will post a photo of my proposed set up… Thanks in advance.
