Choosing a Mounting Location
Choosing a suitable mounting location is the single most important aspect of a successful installation.
KEEP CLEAR AREA
Persons or animals entering the Keep Clear Area may be detected by the field mill as a High Electric Field
or Lightning. If the field mill is mounted at ground level a fence or other barrier should be erected
around the field mill. Keep the area directly under the field mill clear of long grass or weeds. Patio slabs
or a poured concrete pad is recommended for ground installations.
FIELD OF VIEW
The electric field mill requires a view of the sky to detect the static charge on overhead clouds.
Obstructions within the field mills field of view may reduce the sensitivity of the field mill
Secure the tripod to the roof or patio slabs/concrete pad on the ground. For a no-holes tripod
installation on a flat roof the tripod may be secured to patio slabs placed on the roof. Run cables away
from the field mill sensor, not directly underneath.
