4.2. Gate width
The maximum gate distance GD (see manual, Chapter project notes) is 95 cm. The minimum gate
distance GD is 65 cm.
The maximum number of tags, that can move with a maximum speed of 1 m/s through the gate
depends on the number of antennas and the performance of the transponder. For a three antenna
set up it should be possible to read (SNR) up to 10 pieces of ISO15693 transponder at the same
time (see condition at antenna manual, Chapter project notes).
