用愛開新春 300B-1區獅子會喜樂愛相隨 | 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.

獨家報導 李振麟／綜合報導
瑪喜樂基金會長年以來秉持「打造友善職場、提升身障勞動力」為核心，已連續六年間舉辦餐會募款建廠活動，期許能為身障朋友開創就業新天地。今假113年一月二十七日於新北市「海大王時尚囍宴廣場」舉辦首場慈善募款餐會，現場席開約五十桌，愛心滿滿。
國際獅子會300B-1區2023-2024創區首屆總監，鄭興進獅友號召獅友們共襄善舉滿鄉里。鄭興進總監表示：「近幾年全球經濟遭遇新冠疫情、俄烏戰爭與通膨民生衝擊，如今雖見景氣曙光撥雲見日，但是身障朋友們的就業環境仍未走出困境，經濟復甦增長速度也仍緩慢。這場別具意義的公益活動，自去年以來就持續策畫安排中，如今順利透過300B-1區全體獅友與社會企業的共同力量，一起來幫助瑪喜樂完成方舟夢想。」
今日由「國際獅子會300B-1區」擔任主號角，出錢出力捐助50萬元以及「南山人壽」捐助13萬元合辦、新北市「真善美獅子會」捐助6萬元、洪秀菊女士及「福淞企業社」捐助3萬元協辦，再加上近20多個贊助單位同心響應。匯聚眾人善的力量，讓愛滋生沒有距離，成為方舟園區最堅固的基石，讓身障朋友們能有機會一展長才與社會幸福共融合。
瑪喜樂基金會執行長 林玉嫦表示：「感謝北部熱心企業社團乃至於個人，在所有人的善行推動下，造就這場有意義的瑪喜樂盛宴，讓許多身障朋友與弱勢家庭有了安身立命的庇護夢工廠。更感謝國際獅子會300B-1區鄭興進總監與全體獅友們的愛相隨，不僅讓每個人了解到生命的意義與價值，也帶給身障朋友未來的希望，讓愛散播出去。」
