伊朗周四發射飛彈，擊中以色列南部一家大醫院，並襲擊特拉維夫（Tel Aviv）的住宅大樓，導致240人受傷及廣泛破壞。

美聯社20日報導，以色列國防部長卡茲（Israel Katz）將這歸咎伊朗最高領袖哈米尼（Ayatollah Ali Khamenei），並說軍方「已接獲指令，並明白，為了達成一切目標，這人絕不該繼續存在」。同時以軍警告伊朗北部卡拉什·塔萊山（Kalash Taleshan）工業區的居民，將對所謂的軍事基礎設施發動攻擊，要求他們疏散。

另一方面，以色列廣泛打擊伊朗核設施，其中包括位於阿拉克（Arak）的重水反應爐。但伊朗國營電視台說，該設施「完全沒有輻射危險」，並在攻擊前已完成疏散。

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.
