Maximum read/write ranges
7
Please observe the installation notes (Page 9) and antenna alignment (Page 15) to achieve
the maximum read/write range.
The measurements were made under the following conditions:
● Maximum possible radiated power of the reader or antenna
● With a 3 meter long antenna cable with 1 dB cable loss (article number: 6GT2815-
0BH30)
● Room temperature of approx. 20 - 25 °C
● Optimized real measurement conditions (laboratory with few metallic reflecting surfaces)

Maximum write ranges
The antenna requires more power for writing than for reading data. When writing, the
maximum range reduces by approximately 30% compared with the read range.
