持具５０に装着容易なるよう内弧状３８に形成する。The holding portion 31 is set so as to be in contact with the inner surface of the reinforcing rib 22, the back surface of the reflective surface 21, and the side surface of the vertical rib 23.
The tip 31A of the converter 5 attached to the tip of the support arm 30 is formed so that the tip 31A of the converter 5 abuts against the back surface of the reflecting surface 21, and is screwed onto the vertical rib 23 with the screw 61. position at the focal point. Vertical rib 2 of reflector 2
In order to be able to fix the holding part 31 of the support arm 30 to the 3 side surfaces, the back surface of the reflective surface 21, and the inner surface of the reinforcing flange 22, the lower edge 34 of the tip of the holding part 31 is formed so that it can come into contact with the inner surface of the reinforcing flange 22. A protrusion 35 is provided on the lower edge 34 to engage with the front end surface of the reinforcing flange 22. In addition, when attaching the holding part 31 to the bottom of the back surface of the reflecting mirror 2 and attaching the converter 5 to the tip of the supporting part 32, it is necessary to position the primary radiator 4 at the focal point of the reflecting mirror 2. In this embodiment, the lower edge 34 is It is formed to have a slight inclination angle θ with respect to the upper edge of the support portion 32. By configuring the reflector 2 and the support arm 30 in this manner, the support arm 30 can be fixed so as not to move up and down or back and forth by tightening the screw 61 when setting the antenna. When the support arm 30 is folded, it must be able to rotate approximately 90 degrees so that the reflector 2 can be accessed. The support arm 30 is connected to the vertical rib 23
Even if an attempt is made to rotate the support arm 30 by 90 degrees while the support arm 30 is fixed to the It would be better to cut an r-shaped adjustment slot so that the support arm 30 can move backward and upward, but since the support arm 30 and converter 5 are heavy, It becomes difficult to rotate 90 degrees. Therefore, an inverted J-shaped adjustment slot 36 is cut, with its lower end 36A serving as a rotation point and its upper end 36B serving as a fixing point. The adjustment elongated hole 36 has a longitudinal groove cut perpendicularly to the lower edge 34 and a horizontal groove cut parallel to the lower edge 34. When the screw 61 is positioned at the lower end 36A of the hole 36 and rotated, the support arm is closed. Since the rear part of the projection 35 of 30 just hits the reinforcing rib 22, in order to avoid this, it is necessary to form the inner surface of the connecting part 33 into a circular arc surface 37. The tip of the support part 32 is formed into an inner arc shape 38 so that it can be easily attached to the holder 50.

つ折りたためるようにして支持アーム３０の支持部３２
先端に固定できるように形成する。The holder 50 is fastened to the front end surface of the converter 5 with a screw 62, and the holder 50 is attached to the support part 32 of the support arm 30 so that the -order radiator 4 faces the direction of the reflected wave of the reflector 2 and can be folded.
Formed so that it can be fixed to the tip.

る。That is, as shown in FIGS. 7 and 8, the holder 50 projects obliquely from the front end surface of the converter 5 downward in three directions, and the upper and lower edges of the holder 50 are fixed to the tip of the support part 32 of the support arm 30. The guide pieces 51 are bent inward respectively.
・52 is formed so that the tip of the support portion 32 can be slid between the guide pieces 51 and 52. In order to prevent the converter from wobbling at the tip of the support part 32, a straight adjustment hole 53 is formed in the center of the holder 50 so that a screw 63 can slide therein. The screw 63 is inserted into the adjustment elongated hole 53 and fitted into the screw hole 39 at the tip of the support part 32, and a protrusion 54 formed by bending the tip of the holder 50 inward is formed in the engagement hole 40 formed at the tip of the support part 32. is engaged with and fixed to the support arm 30.

Function: When the antenna device constructed as described above is installed while receiving Eika broadcasting, it is fixedly installed and can provide good reception, as shown in FIG. Then, when moving or storing it in a package at the production factory, as shown in Figure 10,
Loosen the screws 63 and 61, remove the protrusion 54 of the holder 50 from the engagement hole 40, pull out the holder 50, fold the converter 5 inward against the support arm 30, and then
The support arm 30 is moved upward relative to the reflector 2 and further retreated, so that the screw 61 is positioned at the lower end 36A so as not to interfere with the reflector 2, and the support arm 30 is moved closer to the reflector 2.
It can be folded to the side into a compact shape.

こともできる。In the folded state, the screw 63 is moved from the fixed position of the adjustment slot 53 when the antenna is installed and is located at the other end. At this time, since the guide piece 52 of the holder 50 is set shorter than the guide piece 51, the converter 5 can be easily folded without interfering with the tip of the support arm 3o. Further, the guide piece 51 is set so as to be able to abut the tip edge of the support arm 30 in the folded state, so that the converter 5 can be fixed without wobbling. Further, to install the antenna, reversely extend it by pulling it out 6, and then tighten the screws 63 and 61 to fix it. At this time, the position where the screw 63 hits the upper end of the adjustment slot 53 and the screw 61 hits the top end 36B of the adjustment slot 36 are set respectively, so by tightening the screws 63 and 61 at these positions, The converter 5 can be fixed at the tip of the support arm 30, and the support arm 30 can be fixed to the reflector 2. If the screw 61 alone is insufficient when installing the antenna, use a screw that can be attached and removed separately to adjust the adjustment slot 3.
6A and screw the support arm 30 through the screw hole 25.
