I am using a alloy telescopic mast 40mm top at about 10m up with steel guys x6,
i get no movement in wind, not even a shimmer when a pigeon lands or takes off
Having said that, my bucket is not up there, i would never put it up there, too big
of an area for the wind to hit and in no way would i put an all in one up there.
I have just had a quick look at a video on your station, can you not separate the
sensors
ps, i read a paper with regrads to urban siting and this paper stated that there is
little difference to mounting the temp at
10m (see edit below), 5m compared
to the same results to an open area, therefore, if you are in a built up area then its
favorable to put the up there, more accurate than at the suggested height.
My temp is at 13ft and i see no difference between that (Davis) and the OS968 at
the suggested height at night time of which i was warned about.
Bear in mind that the suggested height of 2/3ft is for open ground, not ya backyard
Us backyarders have to make compromises here and there.
If you can, split it up, theres nothing to say you cannot mount the rain on the mast
lower down where there is no sway, but, i wouldnt go with fibreglass, they sway a
lot more than their steel or alloy counterparts.
EDIT
RE paragraph 3, I stand corrected its 5m not 10m, after many months of searching for
this paper again, i have finally found it
Paragraph 3.1
