2 Antenna and Range
2.1
Antenna
The system includes an antenna, It is situated within the enclosure (to save penetrating the enclosure)
If the range is inadequate then it may be necessary to mount the antenna protruding from the enclosure. This
may be easily fitted using the provided panel mount BNC socket. The antenna cable may be extended however
please note that typically there is a 50% range reduction with every 3metres of coax cable used!
For increasing range performance a +3dB gain antenna is available. This is supplied with wall mounting bracket
and 2metres of coax cable, it plugs in directly to the BNC connector.
2.2
Range
The antenna choice and position directly controls the system range. Keep it clear of other metal in the system.
The best position is protruding from the top of the product. This is often not desirable for practical or ergonomic
reasons and thus a compromise may be needed. If an internal antenna must be used then try to keep it away
from other metal items, and in particular large ones like transformers, batteries and PCB tracks and earth
planes.
Note that the space around the antenna is as important as the antenna itself. All radio systems are dependant
on a radio signal being received through airspace.
The range quoted is the optimal in direct line of sight without obstacles and in good atmospheric conditions.
2.3
Signal integrity
In systems where many encoders are in close proximity there may be occasions when, due to signal overlay
between encoders, it is difficult or impossible to guarantee system integrity. In such circumstances it is the
responsibility of the installer to ensure that the system performance is adequate for the purposes of the
installation.
