It is typically used in areas of limited space as it can significantly reduce the ground foot print of the antenna without significantly impacting performance. Viewed from the side, it looks like the English letter "V" turned upside down, hence the name. Inverted vee antennas are commonly used by amateur radio stations, and aboard sailing vessels requiring better HF performance than available with a short whip antenna. Inverted vee antennas are horizontal polarized and have a similar pattern compared to a traditional horizontal dipole. ==Use== Typically, the inverted vee antenna requires only a single, tall support at the center, and the ends can be insulated and secured to anchors near ground level or near the roof if mounted on a house. This simplified arrangement has several advantages, including a shorter ground distance between the ends. For example, a dipole antenna for the 80 meter band requires a ground length of about from end to end. An inverted vee with a apex elevation requires only . For radio amateurs living on small parcels of property, such savings can make it possible to use the lower frequency amateur bands. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Inverted vee antenna」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
