3.2 Mounting, Installation and Antenna Connection
3.2.1 Mounting
The diagram below shows dimensions of the transmitter housing for mounting.
Figure 3-10. Mounting Dimensions
When mounting your end device, care should be taken to make sure it is as far
away from any metal objects as possible. If nearby metal gets too close to your
unit, it has the potential to interfere with the way the unit radiates and may cause
signal lose or possibly even the inability to communicate at all with your receiver.
3.2.2 Installation
When installing your End Device it is important to position your device in such
a way as to optimize the antenna location within what’s known as the “Fresnel
Zone”.
The Fresnel Zone can be thought of as a football-shaped invisible tunnel between
two locations that provides a path for RF signals between your End Device and
your receiver.
