If metallic conveyor rollers are a part of an application it’s advised to replace
them with plastic parts if possible or apply shielding techniques as required.
The materials that antennas are mounted on/into should not be metallic or
conductive.
Materials such as wood, laminated MDF, HDF or plywood have a limited
conductivity. If an antenna is mounted into these materials some drop in the
read range is expected in comparison with the equipment specification.
Plastics are the best materials to embed antenna into provided they are
graphite/carbon free.
Try to avoid using black plastics as they may be
conductive due to carbon/graphite based
colouring agents.
Clear glass is generally not conductive and can be used as a desk top
material. Smoked and tinted glass may be conductive and any affect on
antenna operation should be determined by measurement.
Distance
Antennas mounted in a close proximity to each other may interfere with
each other’s operation.
For antennas connected to the same MARS Reader the safe distance
between the antenna edges is antenna size dependent and varies from 5
cm (radius 30 mm round antenna) to 15 cm (202x352 mm antenna).
For antennas connected to two different MARS Readers the safe distance
between the antenna edges is also antenna size dependent and varies from
30 cm (radius 30 mm round antenna) to 60 cm (202x352 mm antenna).
Do not mount an antenna on a desktop surface if there is a MARS reader
immediately below and under the antenna. The distance between the
antenna and the MARS reader should be no less than 20 cm. Use extended
brackets to increase the distance if required. Alternatively the MARS can be
screened from the antenna by a purpose built ferrite shield.
! In general no electronic devices are to be placed within 20 cm
of the antenna in any direction.
Before such installations are attempted Magellan must be
consulted.
Cables
Do not run any cables under or near antenna. Maintain a minimum distance
of 15 cm.
! The cables that connect external antennas with the reader are
provided by Magellan. The MARS Readers should only
operate with antenna cables supplied by Magellan.
!
Any changes or modifications to the equipment that are not
expressly approved by the party responsible for compliance
will void the product warranty.
