五酒桶山「自然野徑」啟用 生態工法開闢手作步道

HA-0218G-NF

Applications:

•  2GHz to 18GHz
•  6061 Aluminum metal alloy
•  Stainless Steel N-female
•  Taiwan Design, Made in Taiwan

Features:

• High Power 300W (peak) 150W (Cont)
•  DC Short lightning protection
•  Low VSWR
•  Uniform Gain
•  Consolidated performance database

The horn antennas of the FT-RF horn double ridged antenna series are characterized by an enormous broad frequency range from 2GHz to 18GHz and very high input powers reach to 300W. The gain increases with increasing frequency up to max 17 dBi. The products are in stock and can be shipped
It is suitable for both transmitting and receiving purposes, especially suitable for microwave and EMC measurements.
This antenna has a more uniform gain and antenna factor because of the better behavior of its radiation pattern.

For EMC/ EMC testing: 

• Pre-compliance testing lowers the chances of certification failure.
  You can make adjustments throughout the design phase with pre-compliance testing.
  Fixing issues after compliance testing are far more costly and time-consuming than fixing them at the design stage.
  Pre-compliance testing might concentrate on the areas where you are concerned about potential issues.
  Instead of looking for faults, pre-compliance testing focuses on identifying solutions.

五酒桶山「自然野徑」啟用 生態工法開闢手作步道 / 記者劉筱寧

桃園市長鄭文燦今(31)日上午前往蘆竹區，出席五酒桶山手作步道啟用儀式及「2022蘆竹出好筍」活動。五酒桶山是深受市民朋友們喜愛的登山聖地，目前已設置6條步道，今日啟用的「手作步道」全長1.4公里，工程經費共1,938萬，採生態工法開闢，減少自然衝擊，施工相當細緻，步道完成後由民眾參與票選，將手作步道命名為「自然野徑」。鄭文燦今日頒發榮譽志工感謝狀，並授旗予五酒桶山公園巡護志工隊，感謝守護公園及步道的奉獻精神。

鄭文燦指出，五酒桶山公園是一個山林公園，也是一個自然生態公園，當初設計公園時，就以步道、草坪、戶外生活為主，目前已完成「環山步道」、「森林浴步道」、「營盤古道」、「六福步道」、「知性古道」、「海山之路」等6條步道，加上今日啟用的「手作步道」，總共7條步道串接成完善的放射狀登山系統，淺山地形爬起來不費力，能輕鬆悠遊在山林之間。五酒桶山是適合全齡登山的生態公園，未來規劃擴大公園的草坪面積，針對一些比較低矮的灌木、雜木區進行整理，希望讓活動草坪大一點、遊戲空間多一點，也將會設置兒童遊戲設施，讓兒童體驗山林美好，從而更喜歡自然。

Double Ridged Horn Antenna
Sort by:Select
The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.

The advantages of Horn antenna:

- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.

- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.

- Easy to make, simple design.

The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.

Recommended Accessories

- Antenna Tripod: easy and fast-changing polarisation. 100% stable handling

- SMA Cable: High-quality special SMA cable

鄭文燦提到，蘆竹區的城鄉距離很短，近山也親水，其中山高大約150-250公尺，非常好親近，包括五酒桶山的7個登山步道，能體驗山林生態，大古山觀景步道可觀賞落日、夜景及飛機啟航，羊稠步道可以看甲蟲生態等，都非常有特色。此外，南崁溪、桃林鐵路、機捷大道等三條都會區綠帶，可以慢跑、健走、騎腳踏車，都讓蘆竹居民的生活更美好。蘆竹區公所主秘詹國華表示，五酒桶山公園於107年開闢完成，接著開闢手作步道時，發現大部分坡度在30％，若開設成車道，將會造成大量生態破壞；因此，鄭文燦指示開闢親山步道，保護五酒桶山的生態資源。五酒桶山自然野徑是全市第一條，從規劃、設計到施作都融合手作步道理念的郊山步道，在工程期間更結合市民參與施作，是友善環境的工程典範。

詹國華說明，不同於傳統步道工程慣用挖土機大興土木，「手作步道」強調以人力方式，運用非大型動力工具輔助步道施工；此外，為保護動物棲地、珍貴植物及人文地景等重要區域，採「之」字形方式選線及克服坡度高差，透過迴避、縮小、減輕、補償等方式，降低對環境的擾動。「手作步道」不使用水泥，改用與現地環境相容的自然材質，施作道路透水鋪面，鋪面踩踏起來柔軟有彈性。全線僅在必要處設置階梯、排水設施，將人為斧鑿痕跡減輕至最低。今日活動結合「2022蘆竹出好筍」農特產市集活動，包括蘆竹綠竹筍產銷班展售、在地特色小農、農場遊程、農事體驗DIY活動等，讓民眾更認識五酒桶山及蘆竹人文之美。
