We provide measurement and calibration Tests, ODM, OEM services for certain products.

We have hundreds of customers from over 60 countries, and to meet their demands, we developed a plant in Vietnam (with a total infrastructure area of 10000 square meters, which includes three major buildings dedicated to operations and production) in addition to the main manufacturing facility in Taiwan. 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

端午連假天氣出爐！擺脫前幾天陰雨綿綿天氣，今（30）日各地多雲到晴，午後山區及大台北、東北部地區有局部短暫雷陣雨，各地高溫都在30度以上，夏季型天氣得小心中暑。不過明天鋒面接近，天氣開始不穩定，全台有雨，午後更得嚴防「非常旺盛的午後雷陣雨」，大台北地區可能會有局部性豪雨！

氣象局資深預報員劉宇其表示，日前的鋒面離開台灣已到華中地區，各地天氣穩定，溫度回升，不過西南風還是帶來水氣，中南部沿海地區從清晨至早上仍有短暫陣雨，中部及南部時晴時雨，北部、東半部午後有雷雨；溫度方面，西半部的內陸地區有機會到34至35度，台東大武很可能會出現36度，氣象局提醒，中午前後更顯悶熱，要防曬並且防範熱傷害。

明周二（31日）又有一波鋒面往台灣接近，帶來不少水氣，明天全台灣都會下雨，尤其中午過後，北部、東半部會有很明顯的午後雷陣雨，不排除會有局部大雨。

氣象局表示，周二的各地降雨會有時序上的不同，一早先是苗栗以南有零星短暫陣雨或雷雨，中午過後各地山區、大台北、宜蘭、花蓮等地會有非常旺盛的午後雷陣雨，不排除會到大雨等級，大台北地區可能會有局部性的豪雨，午後一定得慎防大雷雨帶來的雷擊或是短延時強降雨。

6月1日至3日鋒面稍微遠離，水氣稍微減少，4日之後水氣又稍微增加，降雨範圍又稍微擴大一些，未來一周，中南部時不時陣雨，北部、東半部及各地山區留意午後雷陣雨。各地高溫都會來到32度以上。

「天氣風險 WeatherRisk」粉專也表示，隨著梅雨鋒面北抬遠離台灣，過去這兩天週末假期台灣的天氣恢復夏季型，主要的降雨為山區午後的局部雷雨，平地則大致都是多雲到晴，溫度明顯轉熱，很多地方白天的高溫都來到32-34度以上，很有夏天的感覺。

預估本週梅雨鋒面的位置大部分時間都是比較偏北的，對台灣沒有直接的影響。今周一仍維持夏季型天氣，要留意山區午後發展的熱對流雷雨，並且可能會往大台北、宜蘭、花蓮一帶的平地擴散，西半部平地比較不受影響，午後雲量增多但下雨機會相對較低。

明周二（31日）可能是本周天氣相對最不穩定的一天，因為鋒面位置稍微接近台灣，雖然沒有直接影響，但是會讓台灣上空的雲量增多，大氣也會變得比較不穩定，大環境吹西南風的關係，中南部迎風面有局部短暫陣雨，各地山區的午後熱對流發展變得比較旺盛，北部、東半部平地也會受到影響，有機會出現局部較大雨勢，也可能發生短時強降雨現象。

後天周三（6／1）起一直到端午假期（6／3-5），預期鋒面位置又將偏北，回到長江以南至東海、黃海一帶徘徊，台灣受到大環境西南風影響，配合海陸風環流的日夜變化，中南部迎風面地區在夜間到清晨之間會有局部短暫陣雨出現的機會，各地山區午後也都會有熱對流雷雨發生的情況，平地區域以北部、東半部受熱對流降雨的影響較大，雖然不會有鋒面直接影響，但是天氣狀況仍然不是很穩定，如果有安排假期活動的話還是要多注意一下天氣變化的情況。
