不滿放學被耽誤 夜校生丟蝴蝶炮叫囂

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

新竹縣某高中昨（4日）晚間夜校生要離校時，因不滿校方延遲開校門，一群夜校生不段在校內鳴按喇叭，還丟躑蝴蝶炮叫囂，引來校方注意，隨後開啟校門才一哄而散，影片被Po上網後，引起網路熱議，校方表示將找出相關同學進行輔導，並檢查車廂，避免再次發生。

畫面中，一群被學校鐵門擋住的夜校生，不斷叫囂，要求學校打開校門，因為距離原本要離校的時間，已經晚了將近１個小時，等不下去的學生，最後還拿出蝴蝶炮點燃，朝校外丟躑。

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

校方表示因為附近民眾認為晚上下課車聲過大以及校門口路口怕發生車禍，所以學校要調查晚上夜間部學生下課車流量，不料在21時50分下課時調查車輛過程中，已經超過下課的22時，造成學生不開心起鬨，而後還放蝴蝶炮往校外丟，後面校方人員開啟鐵捲門讓學生離開，其中都沒有人員受傷。

校方表示進修夜間部同學因為年紀較長，所以有騎車開車的需求可以跟學校登記來駛進校內，後面會調閱監視器，將有違規的同學找出來輔導，後面也會檢查車廂背包，避免類似情事再發生。
