ABSTRACT:
A waterproof mechanism for a satellite antenna is to separate a waterproof cover of the known technology into two components of a fixing cover and a thin wall cap used for compressing an O-ring, cause the thin wall cap and the O-ring to be combined closely and stably on the upper end of a wave-guide tube, and enable the stability and the strength of the entirety to be increased. But, the thin wall cap is unnecessary to have a same thickness as the fixing cover. Therefore, the thickness of the thin wall cap can approximately be reduced to 3 mm. This can increase broadly the passing rate of satellite signal and allow a low noise block with integrated feed (LNBF) to have a better satellite signal receiving effect.
