or more, an optional tripod or mast mounting system is required for stability in the field.
The following parts are supplied as part of the field installation kit.
4ft Vertical Pipe, Reducer 2-
1”
1in x 1-1/4 in Reducer
GMX600 Support Tube, 1.

In addition the user must supply the following materials:
2” metal pipe, 6’ long, threaded on one end for 2 in pipe thread.
Concrete (quick set) mix to secure the vertical pipe, and fill a 4 ft hole (1-2 bags). 2-4 gals
water as recommended by concrete mix.
Wooden stakes, and tape to position and hold pipe while setting concrete.
Tools listed in the previous sections
Select site for installing tripod and weather station. The site should be away from obstructions
and sprinklers. A flat ground is recommended for installation, even though the unit can be
installed in many different terrains with some professional help.
Prepare an area of 10’ diameter for installing tripod with little disturbance to the ground surface or
vegetation.
Dig a posthole of 6- 8 in diameter and four ft deep with a shovel or with a posthole digger. Mix
two bags of quick set concrete mix and pour into the hole. Insert the 2” pipe in the pit and fix the
pole position vertically with wooden stakes and tape.
The 2” pipe should extend only two feet above the ground surface.
You may also tap the pole into the bottom of the hole with a hammer as long as the threads are
protected. Then pile rocks or bricks around the pole to hold the position vertical. Check the
vertical pole with a level to make sure it is vertical before leaving for the day. Wait for about 24
hours while the concrete sets.
Apply pipe dope or Teflon tape to threads on the threaded pipes. To prevent cross threading,
hand thread the bell reducer and then tighten with a pipe wrench. Then hand t
hread the 4 ft X1”
pipe mast into the threaded reducer and then tighten with a pipe wrench.
Install aluminum pipe holder
on the end of 4’X1” diameter pipe, both supplied with the weather
station. Adjust to 1 ft. 5 in below the top of the mast, so the cross arm will point roughly east and
west. Tighten the setscrews.
