PURPOSE:To prevent rain or snow from attaching to an antenna and to prevent a drop in I/O gains by providing a hood part covering the antenna plural nozzles feeding air around the antenna and an air compressor supplying air to the nozzles. CONSTITUTION:The titled protector is made up of a base 5, the hood part 6 provided on the upper part of the base 5 so as to face the base 5 and an antenna fitting part 7 linking the hood part 6 and the base 5. The nozzles 4 are disposed at fixed intervals on the edge on the back of the hood part 6. The nozzles 4 feed the compressed air supplied from the air compressor 3, downward(the side of the base 5) through a feed tube 8. If the air compressor is operated in rain or snow, the compressed air is supplied to the nozzles 4 from the air compressor 4 through the feed tube 8. Thus the air prevents rain, snow or dust from attaching to the antenna, whereby a drop in I/O gains can be prevented.
