 of the coaxial connector 126. When the center conductor 129 is moved downward through an insertion hole 135 formed in the insulated housing 122, the stationary terminal 124 stays stationary, and only the movable terminal 125 moves to a position indicated with a hidden line, so that the stationary terminal 124 is disconnected from the movable terminal 125.
When the movable terminal 125 is disconnected from the stationary terminal 124, the center conductor 129 of the coaxial connector 126 is in a state of contacting only with the movable terminal 125. As a result, it is possible to switch a signal circuit between the movable terminal 125 and the stationary terminal 124 to another signal circuit between the movable terminal 125 and the center conductor 129. Here, the change-over operation like this has been used to inspect high-frequency performance of a device equipped with a high-frequency circuit such as a mobile phone.
Conventionally, the coaxial change-over switch 121 has been used solely for inspection and only useful for inspection. More specifically, the coaxial change-over switch 121 has been used only upon inspection of a device after production and usually used only once, and therefore it has not been effectively used. In addition, an outer conductor 128 of the coaxial connector 126 is simply designed so as to be able to engage the lower end section 133 with an annular groove 132 of the coaxial change-over switch 121. Further, the coaxial connector 126 extends in the fitting direction. Therefore, the coaxial connector 126 is not structurally suitable to constantly connect between the coaxial connector 126 and the coaxial change-over switch 121.
In order to solve the above-described problems in the conventional techniques, an object of the present invention is to provide a method of installing an antenna. In the present invention, even when it is not clear whether a wireless module with a built-in antenna should be used or a wireless module using an external antenna should be used, it is possible to select one of the built-in antenna and the external antenna to a situation, and to freely switch between the built-in antenna and the external antenna. In addition, another object of the present invention is to provide a coaxial connector to be used in the method installing the antenna.
A further object of the present invention is to provide a coaxial connector capable of constantly connecting with a coaxial change-over switch, so that the coaxial change-over switch can be effectively used.

When the center conductor 129 is moved downward through an interpolation fix 135 formed in the insulated housing 122, the stationary end 124 stays stationary, and entirely the movable terminal 125 moves to a side indicated with a hidden channel, so that the stationary terminal 124 is disconnected from the movable end 125. 
 When the movable terminal 125 is disconnected from the stationary terminal 124, the center conductor 129 of the coaxial connection 126 is in a state of contacting merely with the movable terminal 125. As a result, it is potential to switch a signal circuit between the movable terminal 125 and the stationary end 124 to another signal circuit between the movable terminal 125 and the center conductor 129. Here, the change - over operation like this has been use to inspect high - frequency performance of a device equipped with a high - frequency racing circuit such as a mobile phone. 
 Conventionally, the coaxial change - over switch 121 has been used solely for inspection and only useful for inspection. More specifically, the coaxial change - over switch 121 has been used only upon inspection of a device after production and usually used only once, and therefore it has not been efficaciously use. In addition, an out conductor 128 of the coaxial connection 126 is plainly designed so as to be able to engage the lower end section 133 with an annular groove 132 of the coaxial change - over substitution 121. Further, the coaxial connector 126 extends in the fitting direction. Therefore, the coaxial connector 126 is not structurally suitable to constantly connect between the coaxial connector 126 and the coaxial change - over switch 121. 
 In order to solve the above - trace problems in the ceremonious technique, an object of the present invention is to provide a method of installing an antenna. In the present invention, even when it is not clean whether a wireless module with a built - in antenna should be used or a wireless faculty using an external antenna should be use, it is possible to select one of the build - in antenna and the external antenna to a situation, and to freely switch between the built - in antenna and the external antenna. In addition, another object of the present invention is to supply a coaxial connector to be practice in the method install the antenna. 
 A further object of the present invention is to provide a coaxial connection capable of constantly connecting with a coaxial change - over switch, so that the coaxial change - over switch can be effectively used.
