The Log Periodic Antenna as known as LPDA is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies.
Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas.
The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements.
With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain.

高齡阿嬤上線聽你吐苦水 1小時要價3000日圓
日本高齡者的工作選擇愈來愈多樣化。一家製作虛擬阿嬤YouTube影片的公司開始招募75歲以上女性，負責從事線上煩惱諮詢服務。這項阿嬤線上諮詢服務已於昨天推出，費用為 60 分鐘 3000 日圓（約新台幣617元）。年輕網友遇到所有煩惱，都可以透過此服務向人生經驗豐富的阿嬤請教，尋求建議。
ITmedia新聞報導，廣島市OTAGROUP公司宣布，正式推出由 75 歲以上阿嬤負責的線上諮詢服務レンタルおばあちゃん。OTAGROUP同時營運由高齡者參與的虛擬Tuber團體「メタばあちゃん（MetaGrandma）頻道。幾位高齡阿嬤在這個頻道化身動漫女主角，分享種種人生經驗。
當有網友申請「出租阿嬤」服務時，營運方會依據諮詢內容挑選合適的長者，透過 Zoom 或 Google Meet 等線上會議工具進行對話。在螢幕畫面上阿嬤會以 3D 虛擬角色方式呈現。這項服務除了線上諮詢外，也接受例如找電影臨時演員等其他實體活動的委託。
