基市中興國小新校舍開學迎新啟用 林右昌：未來區域旗艦學校
In broadcast engineering, a panel antenna is a directional antenna that is widely used to obtain a wireless Internet connection.
Directional antennas receive and broadcast a signal in only one direction, resulting in better signal quality.
Panel antennas, for example, are used in underdeveloped countries to improve the range and functionality of wireless Internet networks.
A panel antenna is shaped like a panel and is typically fixed on a mounting bracket on the exterior or inside of a building. It can also be mounted on a swivel mount, allowing the user to adjust the antenna for optimal signal reception. This type of antenna is usually one-directional, with less mobility side-to-side and up-and-down than an omnidirectional antenna, which can swivel and entirely change its location. Two U-bolt brackets and waterproof were supplied in one piece of packing

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
林右昌指出，中興國小落成啟用，獲得國家卓越建設獎最佳規劃設計類獎項，施工品質優良，爭取公共工程金質獎。這項工程歷經三年時間，在今天開學迎新，也感謝市府各局處與議會對經費支持，立委蔡適應爭取行政院前瞻計畫經費1.5億元設置停車場，市府要求建築師在校園空間設計上，孩子能有寬敞活動空間。
林右昌表示，這項工程整合兩項計畫有了更充裕經費，完成操場、停車場及開放空間，同時對學校和體育館周邊及巷弄道路進行整理，一舉數得。學校未來將是區域旗艦學校，導入雙語學校模式，發展指日可待。
市府團隊積極向教育部，爭取到國小及幼兒園新建校舍經費，加上市府自籌經費，合計總經費3億8,949萬元，拆除使用逾50年的3棟老舊校舍，配合校舍改建將校舍抬高，合併新建停車場，在新學期開學第一天正式啟用。
教育處長杜國正表示，新校舍突破原來校地限制，以創新人字型校舍外觀及新設百米直線跑道、環狀散步空間與一座大型溜滑梯的活動場域，帶給學童歡樂學習環境，同時校舍地坪提升打造，可容納120個汽車停車格和95個機車停車格的地下停車場，除供師生家長停車接送學生使用外，對體育館運動民眾提供便利停車空間。這項工程案參選第22屆公共工程金質獎推薦作業，讓基隆校園施工品質更上一層樓。
教育處表示，施工期間學校以僅存活動中心大樓，作為臨時教室與行政辦公地點使用，師生將教材教具、學生課桌椅及辦公傢俱、卷宗資料，全部搬運至活動中心讀書辦公。歷經三年建置完成後，興建40間嶄新教室及便利停車空間，為師生及市民帶來更新穎、舒適活動空間，成為學校與社區營造，共享共榮的典範。為本市帶來最大公共利益與經濟效益，完善規劃讓學校成為社區中心。
