白家綺暈吐忘記呼吸「痛到像生第5胎」 臉脹紅站不穩挫敗淚：一直禱告
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
白家綺近日為過年節目《民視第一發發發》的演出積極練習「高空U綢」，她說：「因為之前忙著生小孩缺席好多次過年節目的表演，這次打通任督二脈拉筋來表演，痛到眼眶含淚！」過程中白家綺一度因旋轉動作暈吐。
白家綺展開秘密特訓，她說這是自找的，選擇有別於以往的表演突破自己，因表演需要不斷旋轉來完成，她第一次練習15分就下課，高空旋轉讓她頭痛欲裂，形容像孕吐一樣，還差點忘記呼吸，腳已經落地但整個人還是暈到不行，整臉脹紅無法站穩，首次練習坦言讓她非常挫敗，透露人生第一次練習表演要一直禱告，差點要放棄。

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
白家綺需要拉筋來呈現舞蹈動作，不舒服的她頻頻練習「拉梅茲呼吸法」。白家綺苦笑自己的筋很硬，但為了表演必須拉開全身的筋，痛苦到像是生了第5個孩子，每一次都是慢慢進步把身體伸展開，但這過程的痛楚真不是用言語能形容，要趁此機會把平常沒運動的部分補回來，讓體態更完美，再搭配服裝與造型，一定會讓大家在除夕夜驚豔，看到不一樣的白家綺。
