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. ![創作者 periodic 的頭像]()

有關澄清湖球場停車場開放時段,造成台鋼總教練洪一中離場不便,運發局晚間更新說明如下:
高雄運發局長侯尊堯表示,經調查在整個澄清湖球場管理及與球團溝通顯有疏失,即日起撤換球場主任,其他人員調查懲處。
高市府運發局強調,未來必將持續精進球場管理,提供球團與球員更好服務,為高雄棒球賽事環境齊心努力。
