  • Page 2 A UHF tag may have a specific orientation, related to the polarisation of its antenna. A “linear” tag will be orientation-sensitive and will not read as well horizontally as it does vertically. © STid 2014 – No unauthorised reproduction | Introduction NA102A03_EN...

    Ensure the tag is not touching the upper edge of the windscreen. Side to choose according to position of the antenna / reader © STid 2014 – No unauthorised reproduction | Tag position NA102A03_EN...
  • Page 5 2 – The TeleTag is not transferable. When you choose the location, bear in mind the space you will need to insert the tag into the holder (look at the angle of the windscreen). © STid 2014 – No unauthorised reproduction | Tag position NA102A03_EN...

  • Page 7: Basic Installation Rules

    : 0-3 m A higher antenna with a downward orientation will limit the ground range and therefore prevent the tag on a second vehicle being inadvertently read. © STid 2014 – No unauthorised reproduction | Basic installation rules NA102A03_EN...
  • Page 8: Configuration Examples

    External variables can also influence certain functional factors. Simple one-lane access  One URC reader in a lateral orientation  Positioned ahead of the barrier for early detection © STid 2014 – No unauthorised reproduction | Configuration examples NA102A03_EN...
  • Page 9 Double-width sliding gate, with vehicles arriving from both directions  Dual-antenna URD reader or 2 URC readers  One antenna either side of the gate to be aligned with each direction of travel. © STid 2014 – No unauthorised reproduction | Configuration examples NA102A03_EN...
  • Page 10 Each antenna controls one lane and transmits the data it reads to an independent output.  The antenna cannot be further than 9m from the reader, so the reader is located in the centre (red box). © STid 2014 – No unauthorised reproduction | Configuration examples NA102A03_EN...
