けたものである。 Traditionally, parabolic reflectors and radiators have been covered with radomes to prevent antenna performance from deteriorating due to snow or rain. It has also been found that this radome is sufficiently effective in maintaining antenna performance. However, conventional radomes use numerous bolts, springs, etc. to seal the parabolic reflector/radiator. Although it is sealed with a radome, it is impossible to completely seal it, and moisture-laden air may enter the radome, or the temperature difference between the inside of the radome and the outside temperature may cause damage to the inner surface of the radome or the reflective surface of the parabolic reflector. The disadvantage was that dew condensed and formed water droplets, which degraded antenna performance. Furthermore, even if you try to clean the inner surface of the radome or the reflective surface of the parabolic reflector to remove water droplets, conventional radomes use a large number of bolts, springs, etc., so it is not easy to remove the radome. Cleaning the inner surface and the reflective surface of the parabolic reflector was a hassle. Therefore, in order to eliminate the above-mentioned drawbacks, the present invention covers the parabolic reflector and radiator with a radome of a cylindrical body with a bottom and attaches it to the parabolic antenna device, and makes a window hole in the side wall of the radome. A door is provided on the side wall of the radome to open and close the hole.
以下、本考案を添付する図面に示す具体的実施

反射鏡２に取り付ける。 The radome 7 is a cylindrical body with a bottom, and has a flange 7a projecting outward over the entire circumference of the opening, so that the radiator 3 can be accommodated, and the flange 7a can come into contact with the outer peripheral edge of the parabolic reflector 2. It is an insulating material such as synthetic resin formed into a size. Note that the radome 7 is not limited to a cylindrical body, but may be formed into a polygonal cylinder or a conical body with side walls slightly inclined inward, and the bottom may be parallel to the flange 7a as shown in FIG. However, in order to prevent snow accumulation, the upper side may be higher and the lower side may be sloped lower. This radome 7 is attached to the parabolic reflecting mirror 2 by inserting a packing 8 between the flange 7a and the outer peripheral edge of the parabolic reflecting mirror 2, inserting a large number of screws 9, and screwing nuts 10 onto the radome 7.

An arcuate door 12 is connected to the periphery of the window hole 11 via a hinge 13 at one end thereof, so that the window hole 11 can be opened and closed freely, and a handle 14 is fixed to the outside of the other end of the door 12.
A gasket 15 is interposed between the periphery of the window hole 11 and the door 12, and the door 12 is screwed to the side wall 7b with screws 16. In addition, when opening and closing the door 12 even more quickly, it is possible to provide appropriate engagement means on the other end of the door 12 and the periphery of the window hole 11 facing the other end of the door 12 without using the screw 16. In addition, the size of the window hole and door,
The shape and location can be set as appropriate.

易となつた。 As mentioned above, the present invention has an opening/closing door for cleaning, inspection, and adjustment on the radome that covers the reflecting surface of the radiator and parabolic reflector, so that it is possible to prevent the antenna performance from being affected by snow or rain, and also to protect the inner surface of the radome. Cleaning, such as removing water droplets adhering to the inner surface of the parabolic antenna reflector, and inspecting and adjusting the inside of the radome have become extremely easy.
