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.
