|RadioShack weather stations are either wired or, more commonly, wireless. A wireless system has the advantage of not requiring the customer to run wires between the sensors and the main station; however, a wireless system is susceptible to RFI (Radio Frequency Interference). A wired system has the advantage of providing a clearer signal, however, it is limited by the cables, which must be run away from strong magnetic or electrical fields, and which cannot be extended. This last restriction is because the weather station will be calibrated for the exact length of any sensor or transmission wiring involved, except for the AC power wiring. In a wired system, the sensors may be battery powered, or they may be powered via the wiring. In wireless systems, the sensors may be battery or solar powered.
Regardless of the connection method, weather stations operate by using remote sensors to detect weather information (such as wind speed or humidity) and a main console or base to compile and display the weather information.
