港星大陸拍廣告「突然移民」2年 機上晒自拍：降落時可能會哭
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
[周刊王CTWANT] 港星孫耀威1993年在台灣出道，之後轉往香港發展，近2年他待在大陸上海。25日他在臉書貼出一張飛機上的自拍照，他說「2年前本來去內地拍一個廣告，沒想到一走就是兩年多」現在終於回香港，讓他情緒十分激動。

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
孫耀威25日在臉書發文說「2年前本來去內地拍一個廣告，沒想到一走就是兩年多，感恩這兩年多幫我『突然移民』上海的內地朋友們。」孫耀威表示，這2年他過得很充實，經歷許多快樂的事，「但我今天終於要回香港啦！想念我的家！想念我的狗狗貓貓！想念我的家人」，情緒激動的他也說「我想我可能在飛機降落時會哭。」孫耀威在文末標記「86 to 852」，據了解，這是國際電話國碼更改的意思。
此文曝光後，網友紛紛留言回應，「謝謝孫大哥！認識你真好！祝福您和家人疫情期間身體健康平安」、「期待你有機會能來台灣」、「台灣粉絲超級想你」、「恭喜回家了。」
據《維基百科》資料，孫耀威在1993年以專輯《認識你真好》在台出道，發行過20多張專輯，活躍在台港兩地，曾演出《懷玉公主》、《美好年代》等戲劇，2021年他跨入抖音開直播，曾因太多粉絲湧入直播間，造成伺服器癱瘓。
