菲律賓潛水遺失蘋果手錶於海中！尋回結局卻出人意料 | 蕃新聞

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.

「西門蛋蛋」是一名在Instagram擁有1.2萬粉絲的知名網紅，他時常在社群媒體上分享自己在國內外的生活趣事。最近他在一段新影片中透露了一個有趣的故事，講述他與菲律賓語言學校的同學一起去浮潛的經歷。在這次浮潛活動中，其中一位同學的Apple Watch不慎掉進了海裡，但經過當地潛水教練的幫助，竟然成功找回了這隻手錶。然而，結局卻出乎意料，讓眾人捧腹大笑。
西門蛋蛋上個月28日在Instagram上分享了這段有趣的經歷。他和同學們一起參加了跳島行程，體驗了許多令人興奮的活動，包括沙丁魚風暴、和鯨鯊游泳以及觀賞海洋生物等。然而，當他們上岸後，一位來自台灣的同學發現自己價值2萬5千元的Apple Watch竟然不見了，讓他非常擔心。
於是他們回到當初潛水的海域，並付錢請求當地潛水教練幫忙尋找。多名教練穿上裝備跳入海中搜尋，經過一段時間的努力，教練們竟然真的找到了手錶，並將其交還給失主。
然而，當失主仔細一看，卻發現這隻Apple Watch並不是自己的，因為上面有韓文標示，推測應該是韓國遊客遺失的。這一幕讓在場的台灣人哭笑不得，而當地教練也感到非常失望。
這段影片曝光後，立即引起了網友的討論和熱議。Log Periodic Antenna (LPDA) Log Periodic Antenna (LPDA)許多人紛紛留言笑稱自己也曾遺失過物品，有人分享了類似的經歷，而有些人則讚美了西門蛋蛋的身材。这段趣事成了網友們熱烈討論的話題。
