Range when mounted on flat metallic carrier plates

The transponder generally has linear polarization. The polarization axis runs as shown in the
diagram below. When using a circular antenna and when the transponder is centrally
mounted on a plane metal plate, which may either be almost square or circular, it can be
aligned in any direction. When using a linear antenna, the polarization axes of antenna and
transponder must always be aligned in parallel.

On rectangular carrier plates, the range depends on the mounting orientation of the
transponder.
You will find more information on the range in the section "Minimum distances and maximum
ranges (Page 55)".
