and system analysis can all be done from the base station.
Equipment Required:
• Radio
• RF Base Station
• Computer with LoggerNet software
• Antenna and antenna cable
• AC power
1.4 Repeater
Purpose: To act as relay between two communicating stations separated by
too long of a distance or an obstacle which impedes direct
communication. A repeater is not always required in an RF
telemetry network. A field station can also function as a repeater.
