國1楠梓段追撞事故！黑車失控撞護欄翻覆

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

國道1號南下楠梓路段今（22）日下午4時許發生追撞車禍，一輛黑色轎車為了閃避前車，從中線車道變換到內側車道，不慎追撞一輛紅色轎車，黑車失控撞及護欄翻覆，佔用內、中2線道，導致後方車輛一度回堵，國道警方趕抵調查，確認現場無人員傷亡，2名駕駛酒測值為零，確切肇事原因仍待調查釐清。

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

據了解，今日下午4點20分，22歲的蕭姓男子駕駛黑色轎車行經國道1號南下357公里，行駛在中線車道的蕭男為了閃避前車，減速偏移到內側車道，疑因未保持安全車距，追撞32歲鄧姓駕駛的紅色轎車，蕭男失控再衝撞內側護欄，彈飛翻覆在中線車道。

國道警方獲報趕抵，確認現場無人員傷亡，蕭、鄧2名駕駛酒測值皆為零，確切事故原因仍待調查釐清，而該起車禍佔用內、中2線道，一度造成回堵，警方花費約半小時排除現場，解除回堵車流。
