9	9	* Nearby Trees, bushes, power poles etc can induce low period noise in your data when they sway in the wind. A rule of thumb is to have your sensor at least as far away from these as their height.
10	10	* Cattle and stock can and will destroy your site. NEVER EVER install a station where cows can get to it.
11	11	* If the area looks like a place that has flooded, or may flood again, absolutely assume that it will. This very much includes dry riverbeds or ponds. Always prefer locally elevated terranes.

28		-The Trillium Compact 120 and 20 sensors have three adjustable feet for leveling. It is **critical** to "lock" these feet in place by spinning the locking disk upwards towards the sensor, as tight as possible. This reduces "wobble" which shows up in both low and high frequency signal. It is also probably a good idea to keep the length of the three feet as small as possible.

45	45	* Pound in the star picket fence post well away from the sensor hole, and slightly north of it. You will want to then put the fence through the star picket so that it is on the NORTH side. This lets techs "flip up" the fence from behind for easy access.
46	46	* Use wire to secure the fence to the post and also the solar panel to the fence.
47		-* Place the solar panel as high on the fence as possible to reduce any interference from grass and weeds. When securing the solar panel to the fence with wire, make the wire as tight as possible to reduce "rattle" in the wind. Test yourself. It's usually a great idea to use a pair of pliars to make the final twist in the wire so that it is **really tight**.
