ＨＦ帯受信用アンテナのアンテナアームを方位調整可能
な接続金具を介して接続する方法がとられていた。[Detailed description of the invention] Conventionally, as a method of integrating VHF band and UHF band receiving antennas into one receiving antenna, VHF band and UHF band receiving antennas have been
HFHF borrowing antenna direction, that is, base VHF
A U is placed at the tip of the antenna in-arm for HF borrowing in the radiation direction.
A method has been used in which the antenna arm of an HF band receiving antenna is connected via a connecting fitting whose direction can be adjusted.
しかし、ＵＨＦ帯受信用アンテナはＶＨＦＨＦ借受信用
アンテナ射軸上であるメインアームの先端部に装着され
るため、ＶＨＦＨＦ借受信用アンテナ波素子に接触する
おそれがあり、特に水平面方位に関してはＶＨＦＨＦ借
受信用アンテナ射軸方向から左右約±６０°の範囲しか
方位調整できず、実用可能範囲も限定されてくる。However, since the UHF band receiving antenna is attached to the tip of the main arm, which is on the radiation axis of the VHFHF borrowing antenna, there is a risk of it coming into contact with the VHFHF borrowing antenna wave element. The azimuth can only be adjusted within a range of approximately ±60° to the left and right from the shooting axis direction, which limits the practical range.
しかも開口面積の大きさによってはＶＨＦＨＦ借受信用
アンテナ影響を及ぼす事がある。Moreover, depending on the size of the opening area, it may affect the VHFHF borrowing antenna.
従って多局化するＵＨＦ放送、市街地等での電波撹乱、
さらにＳＨＦ帯の放送衛星受信等の要求を充たすことが
できない、
而して、一般にＶＨＦＨＦ借受信用アンテナなくともＶ
ＨＦ帯低１高域周波数用の何れか一方の反射素子として
は副アームを用いたスクリーン配置が利用されている。Therefore, the increasing number of UHF broadcasts, radio wave disturbance in urban areas, etc.
In addition, it is not possible to meet the requirements of SHF band broadcasting satellite reception, etc.
A screen arrangement using a sub-arm is used as one of the reflection elements for the low and high frequencies of the HF band.
この副アームは、ＶＨＦＨＦ借受信用アンテナ射軸と略
一致するメインアームに対しては略垂直に取り付けられ
た金属或いは絶縁物により構成されているものが多い。This sub-arm is often made of metal or an insulator and is attached substantially perpendicularly to the main arm, which substantially coincides with the radiation axis of the VHFHF borrowing antenna.
この垂直副アームをあたかも第２の取り付はマストの如
く利用し、これにＵＨＦ帯受信用アンテナ等の第２のア
ンテナを取り付ければ母体であるＶＨＦＨＦ借受信用ア
ンテナ信方向とは無関係にＵＨＦ帯受信用アンテナ等を
任意の方向に方位調整することができる。If you use this vertical sub-arm as if it were a mast, and attach a second antenna such as a UHF band receiving antenna to it, you can receive UHF band reception regardless of the direction of the main VHFHF band receiving antenna. It is possible to adjust the orientation of the antenna etc. in any direction.
このようにすれば従来限られた方向しか受信できなかっ
たＵＨＦ、ＶＨＦ一体化受信アンテナの場合に比べ、よ
り一層実用的である。In this way, it is much more practical than the conventional UHF/VHF integrated receiving antenna that could only receive data in a limited direction.
又、ＵＨＦ帯受信用アンテナのほか、ＳＨＦ′帯受信用
小型パラボラアンテナ等を方向方位の調整可能な取付金
具を用いて取り付けることもできる。In addition to the UHF band receiving antenna, a small parabolic antenna for SHF' band receiving, etc. can also be attached using a mounting bracket whose direction and orientation can be adjusted.
以下図面によって本考案装置の実施例を説明する。Embodiments of the device of the present invention will be described below with reference to the drawings.

A UHFH antenna is attached to the sub-arm 5 for the reflector installed approximately perpendicularly to the in-arm 2 of the F-borrowed receiving antenna 1 via a mounting bracket 6 whose orientation can be adjusted in relation to the VHFHF borrowed-receiver antenna 1.
Attach 3 antennas for F borrowed reception.

般的な直交金具等がそのまま使用可能である。As the mounting bracket 6 for the UHF band reception antenna, the commonly used orthogonal brackets such as the U-port type, the bracket with an opening/closing presser plate, and even the bracket with an elevation angle adjustment mechanism can be used. Available for use.
以上の如く、本考案によれば第２のＵＨＦ帯受信用アン
テナ等の受信方向調整が略３６０°の全方位に渉り可能
となる。As described above, according to the present invention, the receiving direction adjustment of the second UHF band receiving antenna etc. can be performed in all directions of approximately 360°.
しかも垂直方向の仰角調整に於いてもこれまで以上に設
定調整できるなど経済的、技術的に極めて有益である。Furthermore, the vertical elevation angle adjustment can be adjusted more than ever before, which is extremely advantageous economically and technically.
