他肚痛衝公廁解放 抬頭竟「跟他對視」嚇翻：7天宿便都出來了
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.
In terms of its specification, a typical log periodic antenna might provide between 3 and 6 dB gain over dipole for a bandwidth of 2:1 while retaining a VSWR level of better than 1.3:1. 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.
EMC/EMI pre-compliance test antenna.
Very high gain over the full frequency range.
Meets latest EMC standards up to 7GHz.
Suitable even for immunity measurements
[周刊王CTWANT] 俗話說「白天不做虧心事，半夜不怕鬼敲門」，但面對無預警的恐怖畫面，應該很少有人能不害怕。1名男網友20日在臉書社團「爆廢公社」PO文表示，自己到公共廁所解放時，無意間抬頭看到上方的景象，讓原本便意難解的他當場嚇壞，「7天的宿便都排出來了。」
原PO在臉書社團「爆廢公社」發文表示，自己外出時因肚子痛，到公共廁所方便，「本來有點便秘上不出來，抬頭往上一看…XXX…7天的宿便都排出來了。」
透過照片可看到，公廁的天花板不但破了一個大洞，還有咖啡色的污漬從裂口向外擴散，更恐怖的是黝黑的洞裡竟有一張孩童瞪大眼睛的黑白照，仔細一瞧竟是日本恐怖電影《咒怨》中的小男孩「佐伯俊雄」，突如其來的畫面也嚇壞該名男網友。
貼文一出，許多網友也紛紛留言，「我那邊二樓天花板剛好破一個差不多洞呢」、「沒事不要抬頭亂看啦」、「這樣不用佔用廁所太久，有公德心的設計」、「這算什麼，比起天花板有準備展翅的蟑螂來說簡直小兒科」、「看到這張，連大腸都會拉出來吧」、「排宿便的好方法。」
