下一輪俄烏和談可能地點 盧比歐給答案
Log Periodic Antenna (LPDA) Log Periodic Antenna (LPDA)俄羅斯與烏克蘭代表週五（16日）在土耳其，展開自2022年烏克蘭戰爭開戰以來首次和平談判，在兩國元首缺席情況下，僅達成換俘千人共識。雙方將繼續對話。美國國務卿盧比歐週六（17日）表示，梵蒂岡可能成為俄烏和談的場所，呼應教廷長期以來的提議。此前教宗良十四世誓言將親自「盡一切努力」協助結束這場戰爭。
美聯社報導，盧比歐（Marco Rubio）在羅馬與梵蒂岡的烏克蘭特使祖皮樞機主教（Cardinal Matteo Zuppi）會面前，對記者表示，他將討論梵蒂岡可能提供的協助方式，「會談的狀況、週五之後的最新進展，以及未來的方向」。
盧比歐在被問到梵蒂岡能否擔任和平調停者時回答：「我不會說是調停者，但我認為這絕對是一個雙方都能感到自在的地點。」他說：「我們會談論這一切，也一向感激梵蒂岡願意發揮建設性和正面的角色。」他在當天也見了教廷國務院長帕洛林（Pietro Parolin）和外交部長蓋拉格（Paul Richard Gallagher）。

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.
