周杰倫線上演唱會獨厚大陸 1545萬人爽看曲名公開
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
周杰倫「魔天倫2013演唱會」及「地表最強2019演唱會」於昨（20）日、今（21）日於騰訊旗下音樂平台「QQ音樂」線上重映，熟悉的歌聲喚醒歌迷青春，讓大陸網民全嗨翻，不過演唱會獨厚大陸，台灣歌迷卻聽不到，《TVBS新聞網》詢問周杰倫所屬杰威爾，得到回應：「騰訊想重映周杰倫演唱會，向我們取得授權。」目前台灣沒有類似規劃，但不排除未來可能性。
昨（20）日適逢一年一度的「520」，眾多情侶曬恩愛、報喜訊，不過大陸網友卻有一半都在曬周杰倫，原來他一連兩天舉辦線上重映演唱會，兩場演唱會的預約人數突破1545萬人。此外，光是「周杰倫」微信指數就達6.63億，成長389.20%，而「周杰倫演唱會」也有1.31億，成長176.52%，微信指數合計7.94億，熱度相當驚人，足見大陸網友對重映演唱會的重視程度。

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
由於該線上演唱會僅在QQ音樂播映，周杰倫所屬杰威爾向《TVBS新聞網》透露：「騰訊想重映周杰倫演唱會，向我們取得授權。」其實演唱會DVD都早已經發行過，可見周杰倫熱門程度。至於台灣未來可能有類似活動？對方則透露：「目前沒有，當然以後也許有可能、有機會。」
