Roof Mount
When roof-mounting the sensor assembly the unit should be mounted toward an edge of the roof
(preferably on the prevailing wind side of the building) and it should be installed at least 2-1/2
feet above the roofline. Avoid locating the station near any heat sources such as chimneys or
vents. The anemometer may be separated from the station and mounted separately if necessary to
ensure that it is adequately free from interference. An adapter kit is available through RainWise
called the wind extension kit. 50 feet of cable (maximum length), a support mast, coupling
connector and a cap are supplied in a package. The cost is $50.00.

Transmitting Installation
The MK-III LR series station can transmit up to 1 mile with a clear line-of-sight between the
weather station and the Oracle display or other RainWise receiving unit. The 418Mhz model can
transmit up to 400 feet with a clean line-of-sight.
Things that may reduce or disable transmission include:
•
Metal roofing or siding
•
Brick, stone or cement structures
•
Trees or dense foliage

Installation Steps
1. Secure the support tube in the desired mounting apparatus as described above. Slide the MK
station down over the necked-down section of the support tube until seated and the slot lines
up with the retaining screw. Tighten the screw.
2. Rotate the station until the solar panel faces TRUE SOUTH in the Northern Hemisphere or
TRUE NORTH in the Southern Hemisphere. Once positioned correctly ensure that the
support tube is secure and unable to rotate.
