Quad antenna system (triple aisle)
In case four or more AM antennas need to be installed as one complete system, all
antennas need to be connected as shown in Figure 23.

Figure 23: Quad antenna system
When a receiver is installed between two transceivers (RX1 in the above example), then
this receiver needs to be connected to both transceivers through the analogue receiver
cables to make this receiver detect tags in both aisle 2 and aisle 3.
this receiver needs to be connected to both transceivers through the analogue receiver
cables to make this receiver detect tags in both aisle 2 and aisle 3.
Backfield control is possible on those transceivers that are the first and/or last antenna of
the row and the receiver is connected to BUS A of the transceiver. In this case the
backfield detection of TRX1 can be either enabled or disabled. Backfield control on TRX2
is not possible, since this antenna is installed between two receivers.

If no detection is required in aisle 2, then the receiver cable between TRX2 and RX1 can
be disconnected. Backfield control on TRX1 and TRX2 will then be possible, if required.

Large systems
Large systems (more than 4 antennas) need to be installed as described in the previous
section. If one complete Field Bus is required then all antennas need to be
interconnected with FTP cable.
