Plastics are the best materials on which to mount an antenna provided that 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 (for desktop applications).
Smoked and tinted glass may be conductive and any a ect on antenna operation should be determined by
measurement.
5.2 ANTENNA SEPARATION
Antennas mounted in a close proximity may cause mutual interference.
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 di erent 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 and power adaptors are to be placed within 20 cm of the antenna in any
direction. Before such installations are attempted Magellan must be consulted.
5.3 CABLES
Do not run any cables under or near an 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 be operated with antenna cables supplied by Magellan. Any changes or modi cations to the
equipment that are not expressly approved by the party responsible for compliance will void the product
warranty.
