2.0 EX-10 Exciter Installation
The EX-10 Exciter should be installed two to four feet (70 to 130 cm) from the edge of the entry lane. A gimbal mount is
provided allowing for flexible horizontal and vertical orientation of the Exciter. Antenna horizontal and vertical radiation
patterns are shown below. An Exciter height of five to nine feet above the ground is recommended, with six to seven feet
(180 to 210 cm) being a typical height. The area between the antenna and the vehicle lane must be clear of shrubbery
higher than 3 feet (90 cm). Low growing shrubs are acceptable. Taller plants immediately around the Exciter mounting
pole (to hide the pole) are acceptable as long as they are two to three feet below the aimed antenna within the Exciter unit.
The antenna housing may also be painted to blend in with its surroundings so long as a NON-metallic paint is used.
The Exciter’s response-to-vehicle transponder time is set for typical gate operation use. Contact the factory for high-speed
operations.
NOTE: A Yagi antenna may also be used instead of the standard, integrated antenna, if the installation application so
dictates. Please contact Keri Systems for additional information and ordering of the Yagi antenna.
2.1 Exciter Orientation
2.1.1 Horizontal Plane
The horizontal orientation of the Exciter is set so that the center of the pattern is directed at the right edge of the road,
which permits the left half of the detection pattern to cover most of the entry lane. Refer to Figure 2.
