Commonly the radio communication between receiver and
transmitter in the open field can reach a distance of up to 330 feet
providing that there are no interfering obstacles such as buildings,
trees, vehicles, high voltage lines, etc.
Radio interferences such as PC screens, radios or TV sets can, in
bad cases, entirely cut off radio communication. Please take this
into consideration when choosing standing or mounting locations.
Mounting the Sensor
Important Notes:
On the edge of wind direction sensor, there are four alphabet
letter of "N","E","S" and "W" representing the directions of North,
East, South and West. These are located just under the rotating
hub. The entire sensor array has to be rotated so that the
direction indicators on the wind direction sensor are aligned with
North, South East and West at your actual location. The screw
head attaching the wind direction sensor will be pointing North in
a proper install. A permanent wind direction error will be
introduced if the wind direction sensor is not positioned correctly
during installation.
