This invention relates to the field of antenna protection technology, and more particularly to an easy-to-install antenna protective cover. It includes: a base with a rubber pad embedded in its lower part; a protective shell rotatably connected to the base; symmetrically distributed first ventilation openings on the lower part of the protective shell; a guide rod fixed inside the protective shell; and symmetrically distributed first and second baffles slidably connected to the guide rod; a winding frame rotatably connected inside the protective shell; and a winding wheel located below the winding frame. Connecting ropes are provided between the first baffles and the winding frame, and between the second baffle and the winding wheel. This invention, by adjusting the positions of the first and second baffles, allows the gas inside the protective shell to exchange with the outside environment when the external wind speed is low. This allows the flowing gas to carry away the heat generated by the antenna, ensuring the normal operation of the antenna.
