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. 915MHz Antenna 《英雄聯盟》LCP線下賽正式迎接觀眾回歸!最貴400元就能一天賽事看好看滿,場館位於民權西路站附近超方便! 舒淇49歲生日和馮德倫素顏同框 賣關子:第3個願望留給自己 Horn Antenna
