Lane Configurations for Encompass 4/4800 Multi-
protocol Readers Using an External Antenna
TransCore recommends that traffic be guided through a controlled lane to consistently 
obtain accurate tag readings and to prevent physical damage to the Encompass 4/4800 
Multiprotocol Reader and antenna. The following subsections describe some common 
lane configurations and offer suggestions for positioning the external antenna within 
the controlled traffic flow.
Gate with Center Island Configuration
Figure 2-3 illustrates a typical gate application with the readers and antennas posi-
tioned on a center island to read tags mounted on the inside windshield on the driver’s 
side (United States). The antennas are placed to allow time for the gate to open so the 
vehicle can roll through without stopping while not allowing room for an untagged 
vehicle to be between the vehicle being read and the gate.
