Appendix D Range, repeater, maintenance
and care
The free field range, i.e. the range of the line of sight contact between the trans-
mitter and the receiver is 300 ft under optimum conditions. Walls and even
reinforced concrete can be penetrated, which does, however, reduce the range.
A reduced range can occur due to the following reasons:
- High frequency interference of all kinds
- Built structures of all types or vegetation
- The range of the wind sensor in particular can be affected by metal roofs or
roof insulation made from aluminium laminated glass wool.
- The distance of the transmitter or receiver from conductive surfaces or ob-
jects (or to the human body or the ground) has an effect on the transfer
characteristics and therefore the range.
- Wide band interference in built up areas can reach levels that reduce the
signal-noise ratio throughout the frequency band, which reduces the range.
- Devices with adjacent working frequencies can also influence the receiver.
- Badly shielded PCs can irradiate the receiver and limit its range.
Repeater for range increase
Ranges that are reduced by building parameters can be compensated for by a
special repeater developed for weather stations.
The battery-driven repeater equipped with transmitter and receiver receives the
data of all sensors and re-transmits it with a slight time delay. Housed within a
watertight housing the repeater is suitable for both indoor and outdoor mount-
ing.
Maintenance and care information
Protect the device against dust and dampness. Never clean it with chemical
cleaning materials, use only a soft, dry cloth.
