Introduction
The range of RF transmitters is affected by many conditions, some of which are controllable. A few factors
that limit RF transmission include antenna orientation, radio receiver placement, intervening objects, and EMI
(electromagnetic interference). To obtain maximum reliability and reception range, see the guidelines listed
below for installing an RR433 module.
Antenna Orientation
The antenna orientation on the RR433 affects range and reliability.
• The RR433 module must be installed outside of a metal enclosure.
• To maximize reception range, mount the RR433 with the antenna pointing horizontally, parallel to the
floor or ground.
• Other orientations are possible, but reception range will be reduced.
Radio Receiver Placement
Optimum reception is obtained by installing the RR433 module in an open area.
