位在嘉義東石的永豐爆竹煙火公司於2017年曾經承包國慶煙火,不料18日晚間發生火警,警消到場後拉水線灌救,大約20分鐘就將火勢撲滅,不過消防隊一度接獲通報說火警發生前曾發生爆炸,居民的房子有明顯感受搖晃。另外,當地人也對這間爆竹工廠不陌生,因為短短一年間,這已經是第三次發生火警。

廢棄倉庫全面燃燒!濃煙竄天、火光照亮夜空

警消獲報爆竹煙火公司發生火警,雖然到場時火勢已經不大,但還是小心翼翼在四周灑水降溫,以防萬一。幸好燃燒的只是推放廢棄物的倉庫,但民眾也拍下起火瞬間,只見紅紅火光照亮夜空,遠在百公尺外都能看見。

而這起火警就發生在18日晚間,地點是嘉義東石的永豐爆竹公司,雖然燃燒面積只有25平方公尺,也沒有人受傷,但火警發生前,一度傳出發生爆炸,民眾的住家甚至被震到搖晃。

曾辦國慶煙火!爆竹工廠1年3起火警民眾憂心

警消到場後早就熟門熟路,全是因為這間爆竹公司最近一年頻頻發生火警,去年6月,火藥的原料燃燒,導致一名外籍移工3度灼傷送醫,今年3月也有員工疑似作業不慎,廠房起火,他也被大面積灼傷,加上18日這起火警,已經是1年內發生的第3次爆炸。

而這間爆竹公司在2017年也承辦過國慶煙火,不料最近一年燒不停,是哪個環節出問題,恐怕得好好反省,免得成為當地民眾眼中的不定時炸彈。

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
