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
今（23）日為24節氣中的「霜降」，白天台灣附近水氣仍多，加上東北季風增強，桃園以北、東半部地區及中南部山區降雨機率高，尤其東北部地區、基隆北海岸及大台北山區容易出現局部大雨或豪雨，東部地區也有局部大雨發生的機率，隨著東北季風勢力擴大，晚上之後水氣減少，雨勢有機會趨緩，至於新竹以南大多為多雲，午後有局部短暫陣雨。北部及東北部天氣轉涼，白天高溫約24度，到了晚上則會降到21度左右，其他地方白天高溫仍可以來到27至31度，晚上之後也會轉涼，低溫約23、24度。
氣象專家吳德榮在專欄中表示，此波（21日晚起至23日4時）「共伴效應」帶來的最大雨量雖不及上波，但也已超過430毫米（宜蘭南澳鄉）。今日清晨截至4:53各地區平地最低氣溫為：北部（桃園楊梅區）20.5度，中部（南投中寮鄉）21.8度，南部（台南白河區）22.3度，東部（宜蘭五結鄉）21.9度。

今晨北台已有明顯降雨，迎風面有較多的降水回波。最新歐洲模式（ECMWF）模擬顯示，白天迎風面仍有較大雨勢，尤其東北部、北海岸、及北部山區；對含水量已達臨界值的山區，仍有「致災」的威脅；應持續注意！背風面新竹以南大多為多雲時晴，偶有局部短暫飄雨的機率。今日冷空氣南下，北台氣溫漸降、濕涼微冷，中南部氣溫略下降。各地氣溫：北部18至25度，中部20至31度，南部21至32度，東部19至29度。
最新模式模擬顯示，明（24）日起至週四（27日）天氣好轉，各地大多晴時多雲；東北部及山區偶有零星少量飄雨的機率。明日、週二（25日）北台白天舒適、中南部微熟，早晚偏涼微冷；週三（26日）、四各地白天氣溫回升，早晚仍偏涼微冷。明晨至週三晨平地最低氣溫大約降至17度左右。
最新模式模擬顯示，週五、六（28、29日）迎風面水氣增多，大台北、東半部有局部短暫雨，桃園以南晴時多雲，氣溫逐日回升。
