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.
(中央社訊息服務20240712 11:58:31)「北貢寮、中王功、南墾丁」，王功漁火節，邁入20週年，是中台灣最盛大的海洋音樂會，彰化縣長王惠美邀請大家一起嗨翻天！吃喝玩樂拿獎金！
今年活動盛大有三大亮點，包括在王功漁港有水陸氣墊樂園、千人烤蚵、祈福嘉年華、連續二天在晚上8點有7分鐘璀璨煙火秀、無人機及燈光秀、還有壓軸海洋音樂會，將由五堅情、麋先生、魏嘉瑩、陳孟賢等11組樂團歌手接力演出。另外在福海宮連續二天都有擲筊擂台賽，每日最高獎金1萬元。歡迎全國鄉親，7／13、14 相約彰化王功見！
活動期間為有效疏通人潮，每日上午9點至晚上10點在王功漁港至福海宮區間，提供定點免費接駁車服務，另外也規劃彰化火車站往返王功福海宮的直達專車，歡迎民眾多加搭乘利用。
