Description

  The present invention relates to an indoor / outdoor antenna for receiving terrestrial signals, for example, digital terrestrial broadcasting signals, and more particularly to an indoor / outdoor antenna that can be installed indoors or used outdoors. .

  In the conventional indoor antenna, for example, a side plate for supporting the support column is established on the upper surface of the support base that can be placed on the table, and the support column can be raised and lowered. A configuration in which the antenna is pivotally attached and an antenna is mounted on the upper portion of the support is known (for example, see Patent Document 1).

JP 9-326621 A

In the case of the above configuration, when receiving, the antenna can be received if the directivity of the antenna is made to correspond to the radio wave arrival direction. As an operation in that case, the direction of the support base is changed in order to point the antenna in the direction of arrival of the received radio wave. As a result, the azimuth angle can be freely changed.
However, since the cable is connected to the support base, when the support base is rotated, the cable moves together. In that case, if there is a table placed object such as a vase on the table, there will be a problem that the vase or the like may be knocked down depending on the case.

The purpose of the present application is to provide an indoor and outdoor antenna that can be easily installed and used indoors, and that can be easily installed and used not only indoors but also outdoors. It is something to be offered.
Another object of the present invention is to provide an indoor / outdoor antenna capable of adjusting the azimuth angle not only when installed indoors but also when installed outdoors.
Another purpose is to provide an indoor / outdoor antenna that can be easily and firmly configured, even if the antenna can be easily installed not only indoors but also outdoors. is there.
Other objects and advantages will be readily apparent from the drawings and the following description associated therewith.
