The power plant is located in Bory Tucholskie, in a place where there is no telecommunication link. Therefore, to send and receive data to/from power plant we use the wireless cellular network. The power plant uses the directional Yagi antenna working in the 900 MHz band, which is pointed in the direction of the nearest BTS station in Lniano village. Because the plant is situated among the trees and also in the basin, the radio signal from the BTS is relatively weak. Therefore, the antenna was placed on the mast, to get a better signal.
