Log Periodic Antenna

Sort by:Select
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

上半場進帳17分的湖人戴維斯（Anthony Davis），下半場只得2分，這讓騎士將比分拉開，最終以14分之多獲勝，戰績8勝1負，僅次開季拿下9連勝、至今未嘗敗績的密爾瓦基公鹿，在東區排名第2。

賈蘭德（Darius Garland）此役為騎士貢獻24分，艾倫（Jarrett Allen）有16分、11籃板進帳，雷維特（Caris LeVert）和替補的洛夫（Kevin Love）分獲12分、10分。

騎士在開季首戰吞敗後，打出一波8連勝，這是騎士於詹姆斯2017年最後一季於他們陣中效力時拿下13連勝後，最長的連勝紀錄。

湖人上半場一度領先12分，上半場打完也還握有6分領先優勢，但下半場進攻大當機，被騎士打出56比36的半場攻勢，最終只能無奈吞敗，目前戰績2勝7敗，在西區只贏休士頓火箭（1勝9敗），排名倒數第2。

詹姆斯此役攻下湖人全隊最高的27分，戴維斯有19分、12籃板的雙十表現，板凳出發的衛斯布魯克（Russell Westbrook）拿下19分，並送出10次助攻，但有7次失誤。布朗（Troy Brown Jr）則有12分進帳。
