Model 1012 Radio Installation - OPTICOM 764 Installation Manual

3.1.2 Model 1012 Radio Installation

This section describes how to install the Model 1012 version of the Opticom™ GPS radio.
Important Note:
The Model 1012 radio is designed to be installed directly inside of the traffic cabinet with the antenna
mounted on the roof of the cabinet. This style radio should only be installed if it is determined from a site
survey that the location will not overly degrade GPS reception and or radio transmission and reception.
Since the antenna is mounted at the height of the top of the traffic cabinet rather than at the height of the
traffic signals, the antenna's view of the sky (for GPS reception) may be less. Also by mounting the
antenna lower, obstacles such as buildings, trees etc., will likely reduce radio range. If it is determined by
survey of the intersection that these reductions will still allow the Opticom GPS system to operate
satisfactorily, then the Model 1012 may be installed. If not, it is recommended that a Model 1010 radio
be used.
If any of the following conditions are present, the model 1012 is not recommended:
•
Cabinet located under bridge, in another structure etc.
•
Downtown areas
•
Trees over the cabinet significantly obstructing the view of the sky
•
Buildings close to the cabinet significantly obstructing the view of the sky
•
View of approaches obstructed by buildings, signs etc.
•
Nearby bridges blocking view of approach
•
WAAS satellite/s not in view
•
High speed roads that need maximum range
•
Intersections with long ped clear, min greens etc.
•
Pole mounted cabinets
•
Where white colored dome on cabinet is not desired
•
If pole mounted Model 1010 significantly improves performance
•
Vandalism concerns
IMPORTANT NOTE
Modifying the radio/GPS unit may seriously
damage the equipment and void the warranty.
Do not attempt to modify the radio/GPS
circuitry in any way. Modifying the radio and/or
antenna in any way may cause the radio to
violate FCC/IC requirements.
