General
Remember the following when installing the Antenna Reader:

Antenna Reader Distance

The ideal cable distance between the Terminal, Controller or Receiver and its Antenna
Reader ranges between 2 m to 16 m (7 ft to 53 ft).
NOTE: When used with the Impro iTT or the IXP20 Controller (iTT Platform) the
ideal cable distance between the Terminal or Controller and Non-keypad
Antenna Readers ranges between 2 m to 25 m (7 ft to 82 ft). The ideal
cable distance between the Terminal or Controller and Keypad Antenna
Readers ranges between 2 m to 16 m (7 ft to 53 ft).
Optimal performance is not guaranteed outside of the range. Achieve optimal
performance by using a good quality shielded multi-strand 3-pair twisted cable. The
cross-sectional area of the cable must not be less than 0.2 mm
