【旅遊經 編輯部報導】

太魯閣國家公園中的砂卡礑步道及得卡倫步道一直受到遊客喜愛，但為了安全等因素，相關步道將進行護欄及鋪面改善工程，請注意步道施工管制及安全！


其中，砂卡礑步道步道於今(3)日至6月16日止，施作步道1K+600處(五間屋後柵門起)至3K+800處，步道採封閉管制，步道入口至1K+600五間屋路段仍開放，民眾可走到五間屋後折返。

得卡倫步道施作日期於今(3)日至9月8日止，步道封閉管制，遊客可經由太警隊旁臺地步道南段及水管路步道往大同大禮地區。

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

太管處表示，請遊客配合步道封閉管制措施，工程如受天候影響而延長或改變施工期間，太管處將另行公布周知。
