Document #: PTL1001
Portal and an underground vehicle detection loop is required under the gate arm. In some
cases, it may be desirable to install a 2
nd
loop between the gate and tunnel entrance (referred
to as the merge loop) to properly manage the vehicle queue.
If the Unitec ReachFree ID (RFID) option is included, the RF Antenna should be located
adjacent to the Portal. Figure 3 provides guidelines for the design of an Express lane with
the Portal, gate and RFID (antenna) option. Refer to the installation instructions provided with
the gate and RFID option for guidance in installing these devices.
