Now, we are focusing on automatic production lines and investing in automation equipment. In the future, we pledge to deliver the highest-quality product in the shortest possible period.
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
把握好天氣！氣象局指出，今（20）日下午有一熱帶性低氣壓生成，預估21日晚起會對北部、東半部帶來明顯降雨，22日雨勢最大，同時也是熱帶性低氣壓最靠近台灣的時刻。
氣象局表示，台灣東南方海面有一個熱帶性低氣壓生成，預測未來路徑會往西，在22日的時候通過巴士海峽，此時，它的外圍雲系將會為北部與東半部帶來明顯的降雨。21日白天時，只有基隆北海岸、大臺北山區與宜蘭會有零星降雨，其他地區均為多雲到晴的天氣。
氣象局提醒，21日晚上開始，受到熱帶性低氣壓外圍雲系的影響，北部與東半部的降雨明顯，中南部山區也有局部降雨，其中宜蘭有局部豪雨發生的機率，大臺北山區與基隆北海岸也可能會有有局部大雨的狀況。
22日與23日時，熱帶性低氣壓將通過巴士海峽進入南海，此時，其外圍水氣將移入臺灣，北部、東半部地區及恆春半島出現局部短暫陣雨的機率提高，其中基隆北海岸、大臺北山區雨勢較大，在東北部地區的降雨尤其明顯，可能有局部大雨或豪雨發生，而中南部雲量稍增多，在山區也有零星降雨的機會。
氣象局指出，未來一周內，海面上仍有熱帶系統發展的機率，惟其強度、位置及路徑仍有不確定性，請民眾周末時要多留意熱帶性低氣壓的動態。
「台灣颱風論壇｜天氣特急」粉專於臉書透露，熱帶低壓（25W）移動速度較快，將於22日凌晨至上午時通過巴士海峽，強度介於熱帶低壓或輕度颱風等級，要看這兩天內發展的速度而定。周末時受到外圍水氣影響，北、桃、基、宜、花東、恆春與北部山區容易下雨，尤其22日時東北季風增強，又會有類似共伴效應發生，雖然雨勢不會如尼莎颱風來臨時那麼誇張，但仍得留意局部強降雨的狀況。

天氣職人吳聖宇也於臉書說明，從預報路徑來看，熱帶低壓21日晚會接近台灣東南方，周末期間會通過巴士海峽趨向南海，路徑上類似前一個尼莎颱風，北側的環流將對台灣周末的天氣造成影響，請民眾要留意。（封面示意圖／東森新聞）
