Communications
Location of a ground antenna to be used for gate authorization is normally a matter of locating
the ground antenna in advance of the gate to ensure communications and providing an 8-10
feet clearance between the vehicle and gate. One of each type of vehicle to be fueled should be
modified with G-Ring and VM in accordance with instructions found in C35699 Vehicle
Module Installation Manual. Before starting the ground antenna installation, each vehicle type
should be measured, and dimensions that locate the G-Ring in respect to the vehicle front
bumper recorded. These dimensions are then used to design and lay out the ground antenna
installation. For a site using ground antenna communications for fueling and gate use, use the
instructions in the next section
“Antenna Parameters for Fueling with Fuel Point Ground Loop
Communications” on page 10 to locate the G-Ring on the vehicle.
Note: Vehicles equipped with G-Ring that travel over the ground antenna at speeds of 15MPH
or greater will not be authorized.
