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.
主掌西班牙發電的伊比德羅拉公司(Iberdrola)執行長警告稱，如果西班牙重蹈德國關閉核電站的「大錯誤」，那麼西班牙也會重蹈德國缺電又高電價的困境，屆時可能會上漲 25% 以上。
公司執行長加蘭 (Ignacio Galan) 向英國《金融時報》表示，馬德里目前仍在實施「到 2035 年淘汰7座核反應爐」的計劃，他直率的說「這是錯誤的，該結束了。如果執意廢核，西班牙民眾未來將支付更貴的電價，還只能用不可靠的電力品質。」
他表示，政策制定者需要採取「實用主義」，並指出全球都正在轉向延長核電廠的使用年限。
