Site Installation Guide
This guide includes procedures for installing your WeatherHawk station on a tripod or pole, on the ground
or a rooftop, and for installing our associated mounting/installation kits as required. Before installing your
WeatherHawk at your site, read over the sections on power sources, site selection, and communications
considerations. The installation procedures start on page 4.
Power Sources
WeatherHawk weather stations are provided with an internal sealed rechargeable lead acid battery that
must be recharged to assure continued system function. For recharging the battery, WeatherHawk offers
solar panels or an AC/DC converter (see Appendix A: WeatherHawk Equipment). If no power supply has
been ordered, you must provide an external DC power source that has an output of 18 V @ 1.2 amps.
Connecting an incompatible power source to your WeatherHawk voids your Warranty. Please
check with WeatherHawk Customer Service before connecting a power source not purchased
from WeatherHawk.
Site Selection
Ground Installations
The ideal WeatherHawk site is level and well away from obstructions such as buildings, trees, and steep
slopes. If obstructions exist, use the “Ten Times the Height Rule”, which is illustrated in Figure 1.
Figure 1: Ten Times the Height Rule.
n example, if the height of the
WeatherHawk is 5 feet, the height of the
tree, T, is 13 feet and the height of the
shed, H, is 12 ft then the WeatherHawk
station should be placed at least 80 ft
away from the tree (i.e., 10T = 10x [13-
5] =80 ft) and 70 ft away from the shed
(i.e., 10H = 10x [12-5] = 70 ft).
