The 8.8 m cable will provide a range reduction of between 15% to 20 % in comparison to the 1.5 m standard
cable (Refer to the 7.3 Maximum Read-Write Distance).
Method 1
To con r m optimum antenna operation measure the maximum read-write distance.
Take a single tag and position it over the reader antenna center. Do not hold the tag antenna coil or
tag inner area with your  ngers. Preferably hold the tag edges or use a non metallic carrier to hold
the tag.
Measure the maximum read distance in mm and compare with the value for the same antenna-tag
type as indicated in the Maximum Read-Write Distance chart. (Appendix 7.3 of this manual.)
If the maximum read-write distance is less than shown in the chart re-tuning may be necessary. If
the antenna is correctly tuned then the user should determine if the reduced read-write distance is
acceptable.
Method 2
During an initial tuning procedure measure the maximum voltage using an Antenna Tuning Probe. Record the
voltage value and RCA cable length for every antenna. To con rm tuning at any time measure the maximum
voltage using the Antenna Tuning Probe and compare with the recorded results. The voltage values should be
identical otherwise the antenna has to be re-tuned.
