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

近來連日陰雨，不免讓人感到心情鬱悶，中央氣象局表示，未來一週，鋒面在台灣附近徘徊，水氣偏多，比較容易下雨，但並非數日大雨狂炸沒有半點停歇，比較像是天氣不穩、偶爾一陣雨來又雨停，這樣的天氣將會持續1週左右；其中，下週二至週五又因為西南風帶來暖溼的水氣，降雨會比其他時間明顯，外出請攜帶雨具備用。

至於氣溫方面，氣象局表示，未來一週沒有顯著冷空氣南下，氣溫變化不大，各地低溫普遍在22度以上。北台灣白天高溫可達28度，中南部29至31度，花東地區27至29度，氣溫涼爽與否和下雨程度有關，下雨時間若長一些，高溫就會下降2至3度，整體而言，是下雨稍微舒適、無雨時潮濕悶熱的感受。

氣象局進一步分析，下週一（5/23）鋒面位於台灣北部海面，逐漸接近台灣，各地水氣多，北部及東半部地區有局部短暫陣雨，其他地區為雲多，卻還沒有大範圍、長時間下雨。中午過後，南部、中部山區的降雨來自熱對流發展帶來的局部短暫雷陣雨，晚上開始隨著鋒面抵達，北部的降雨的頻率就會增加。

氣象局提醒，下週二至週五（5/24-27）是鋒面影響的最主要時間，同時伴隨暖溼的西南風，西半部及東北部地區有短暫陣雨或雷雨，並有局部大雨發生的機率，其他地區有局部短暫陣雨或雷雨。此段期間大氣的不穩定度比較高，有可能伴隨中小尺度的對流系統在鋒面附近發展，隨機出沒在西半部、東北部地區，一有蹤跡就需要注意突然發生的短延時降雨。

下週六、日（5/28-29） 鋒面有北移的趨勢，環境水氣尚未明顯減少。

環境維持西南風，中南部天氣還是不穩定，偶爾還是有旺盛的對流，天氣為短暫陣雨或雷雨，其他地區則有緩和的趨勢，劇烈天氣發生的機率降低。
