3. Avoid wind obstructions. The rule of thumb is to install the anemometer at least four times the
distance of the height of the tallest obstruction. For example, if the building is 20' tall, and the
mounting pole is 6' tall, install 4 x (20 – 6)' = 56' away.
4. Wireless Range. The radio communication between receiver and transmitter in an open field can
reach a distance of up to 300 feet, providing there are no interfering obstacles such as buildings,
trees, vehicles, high voltage lines. Wireless signals will not penetrate metal buildings. Under
most conditions, the maximum wireless range is 100'.
5. Radio interference such as PCs, radios or TV sets can, in the worst case, entirely cut off radio
communication. Please take this into consideration when choosing console or mounting locations.
Make sure your display console is at least five feet away from any electronic device to avoid
interference.

7.3 BestPracticesforWirelessCommunication
Wireless communication is susceptible to interference, distance, walls and metal barriers. We recommend the
following best practices for trouble free wireless communication.
1. Electro-Magnetic Interference (EMI). Keep the console several feet away from computer monitors and
TVs.
2. Radio Frequency Interference (RFI). If you have other 433 MHz devices and communication is
intermittent, try turning off these other devices for troubleshooting purposes. You may need to relocate the
transmitters or receivers to avoid intermittent communication.
3. Line of Sight Rating. This device is rated at 300feet line of sight (no interference, barriers or walls) but
typically you will get 100feet maximum under most real-world installations, which include passing through
barriers or walls.
4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum siding. If you have
metal siding, align the remote and console through a window to get a clear line of sight.
The following is a table of reception loss vs. the transmission medium. Each “wall”orobstruction decreases
the transmission range by the factor shown below.
Medium RF Signal Strength Reduction
Glass (untreated) 5-15%
Plastics 10-15%
Wood 10-40%
Brick 10-40%
Concrete 40-80%
Metal 90-100%
