No - podla fotky este nie je celkom dobre mozne urcit na co ta antena funguje, ale nieco podobne som videl uz aj ja... Osobne pochybujem o to, ze by islo o nejaku freeband bezdrotovu siet.
Moze it o:
1. antenu na pripojenie terminalov (napr. stavkova spolocnost TIPOS si v pasme niekolko MHz prepaja svoje stavkove terminaly)
2. antena na spustanie systemu varovania obyvatelstva - t.z. radiove ovladanie sireny
3. asi najpravdepodobnejsia verzia - bezdrotovy zabezpecovaci system niektorej SBSky. Niektore bezpecnostne sluzby si v pasme niekolkych MHz posielaju data na pult centralnej ochrany - t.z. dvojcestna komunikacia so zabezpecovacim systemom v strazenom objekte... Tu v Nitre ma na to licenciu CORADO SOAT. |

| Je to potom naozaj nejaka siet - mozno telemetria - ovladanie technologie cerpacej stanice, plus mozno nejake dalsie komuniakcne kanaly - na zabezpecenie objektu, a zabezpecenie hygieny pitneho zdroja atd... - presne vyuzitie ti budu vediet povedat iba priamo vodari - ale funguje to fakt v pasme MHz - aby to prechadzalo aj cez drobne prekazky - stromy, kopec a pod... |

Suhlasim  ... moze to slusizit aj na zber dat ... v BB sa robi zber z kotolni cez WiFi trocha mi to vadi ze kazda kotolna pecie na 2,4 Ghz. .
Avsak to co je na foto je okolo 430 Mhz podla mna. |
