To ensure optimal performance of the MS27102A Remote Spectrum Monitor, conduct a site survey to determine the optimal placement of the instrument for maximum range, coverage, and network integrity. The site must have available utilities (power and network connection). A site survey accounts for the following:
• Location: The instrument and antenna must be placed in an area that is accessible for routine inspection and servicing. The antenna must be placed such that obstructions to the radio signal path are minimized and that the antenna is installed in a safe location, away from interfering signals.
Danger
Avoid installation in hazardous locations such as in an area where the antenna could fall on power lines and result in electrocution or damage to the instrument and connected utility systems.
• Power: Ensure that an available AC line power connection is close enough to the instrument’s DC power supply.
• Ethernet: The Ethernet connection is ruggedized and weatherproof, and supports up to Gbit CAT6 LAN installations. For consistent operation, ensure that the cable run length to the network switch or repeater is less than 100 meters (328 feet).
• Antenna: Proper antenna type and placement is essential for maximizing radio coverage and range. Prioritize antenna height over ground, then antenna gain for increasing the coverage area and range. Consider a directional antenna and its orientation when maximum range is required. Consider an omni directional antenna when maximum coverage area is required.
Mounting Considerations
The MA27102A Remote Spectrum Monitor is designed to be IP67 compliant and can be mounted either indoors or outdoors. The instrument should be installed with the connectors facing downward to provide additional protection from water seepage into the instrument chassis. In extremely harsh environments, additional shielding from direct sunlight in hot climates should be considered. The mounting location must also facilitate clearance to all of the connectors, and cabling should be of sufficient length for servicing.
