Gate Setup with three or more antennas
The mounting manual M50700-4e-ID-B of the antenna ID ISC.ANT1400/760 describes the mount-
ing, cabling and configuration of the set up with two antennas. This application note describes the
necessary changes for a set up with three, four or five antennas.
The manual for antenna ID ISC.ANT1400/760 is the primary reference - please study this manual
first. Mechanical issues are only described in this manual.”
Although theoretically, set ups of up to 8 antennas are possible due to the multiplexing and neces-
sary extra cable length, reading speed will go down and the reading distances will be less.”
Notes:
Before installing the antennas please read the mounting instruction “4.1 Project Notes” in
M50700-4e-ID-B-pdf. The spacing of the antennas gates depends on the antenna
configuration.
If multiple antennas or gates are connected to different Readers, a minimum separation of
8 m must be kept between the antennas or gates. For shorter distances (1 m – 8 m) the
Readers must be multiplexed. Below a distance of 1.5 m the antennas must also be shielded
from each other. Otherwise the Reader range will be significantly reduced. The antennas
must have a minimum distance of 20 cm from all larger metal parts! At a distance of less
than 50 cm between the antenna and metal parts the Reader range will be significantly
reduced.
