3.3 Radio range
The range of a radio link with MIQ/Blue PS SET in the free field is up to
100 m with installation and testing according to this chapter (see
chapter 6 T
ECHNICAL DATA ).
As with any other radio technology, the following points have to be
observed when installing the MIQ/Blue PS SET:
 All materials (even window glass) in the radio link reduce the range.
Therefore, keep the radio link free of barriers (even temporary
ones). Both MIQ/Blue PS modules should be in permanent "visual
contact" through the air. Take into account that there may be short-
time events such as trucks driving by that interrupt the radio link.
 Water, snow and ice on the antenna will reduce the range. When it
is installed in the free field, protect the MIQ/Blue PS against water,
snow and ice. Use the plastic canopy SSH/IQ for this.
Canopies made out of metal or PVC reduce the range!
 A high location of the MIQ/Blue PS increases the range. If neces-
sary, install the MIQ/Blue PS higher over ground.

 Install the MIQ/Blue PS where the mentioned requirements are best
available and establish the connection to the IQ S ENSOR N ET island
with the aid of the SNCIQ cable. Do not in any case use an antenna
extension cable to improve the position of the antenna alone.
Antenna extension cables cause range losses.
 Mount the MIQ/Blue PS outside of a building on a pole and run the
SNCIQ cable through the wall to the next MIQ module.
