    Acuator sau Actuator?!
    Actuatorul este "motoru" antenei parabolice.

    urmarirea orbitei lui clarcke se bazaza pe rotirea antenei in jurul unei axe paralele cu axa pamintului ( antena fiind inclinata data de axa de rotatie cu un unghi numit declinatie avind rostul de a corecta eroarea ,, de paralaxa " )
    mecanismul care realizeaza aceasta se numeste montura polara , actionarea fiind asigurata de actuator .
    practic actuatorul si partea mobila a monturii polare sint un mecanism biela-manivela care transforma miscarea rectilinie a capului actuatorului in miscare de rotatie a partii mobile a monturii polare .
    comanda miscarii se face de un aparat electric numit pozitioner care comanda motorul actuatorului .

    cind cele trei ( montura polara ; actuatorul si pozitionerul ) int integrate in acelasi aparat , acesta se numeste motor h-h
