The horn antennas of the FT-RF horn double ridged antenna series are characterized by an enormous broad frequency range from 2GHz to 18GHz and very high input powers reach to 300W. The gain increases with increasing frequency up to max 17 dBi. The products are in stock and can be shipped
It is suitable for both transmitting and receiving purposes, especially suitable for microwave and EMC measurements.
This antenna has a more uniform gain and antenna factor because of the better behavior of its radiation pattern.
For EMC/ EMC testing:
- Pre-compliance testing lowers the chances of certification failure.
You can make adjustments throughout the design phase with pre-compliance testing.
Fixing issues after compliance testing are far more costly and time-consuming than fixing them at the design stage.
Pre-compliance testing might concentrate on the areas where you are concerned about potential issues.
Instead of looking for faults, pre-compliance testing focuses on identifying solutions.
以〈恰似你的溫柔〉走紅數十年的歌唱藝術家蔡琴，受雲門創辦人林懷民邀請，將於12月22日、12月23日、12月25日舉辦3場《蔡琴在雲門》演唱會，而12月22日更是蔡琴的65歲生日。兩人4日一同出席記者會，蔡琴自稱16歲就是雲門舞集的粉絲，非常感謝林懷民邀約時說了一句很棒的話：「蔡琴，我要妳的聲音浮起來！」能跟林懷民合作「是我的一個夢」！
兩人首次合作「比龜毛」，林懷民擔任藝術總監，他爆料蔡琴第一次到雲門看場地，因為沒帶麥克風感覺不對，之後又帶了麥克風再去一次，像看風水一樣很認真。後來蔡琴還把整個樂團拉到她家裡面去練唱，邊唱邊挑剔自己、挑剔樂隊，「距離演出還有9個月，她在家裡就拿著麥克風、穿著高跟鞋唱。」
蔡琴則說：「他說我龜毛！你們還沒有看到他怎麼折磨我？我都心甘情願、受之如貽。」她舉例光是演唱會要穿什麼衣服，他就挑了很久，如何走位也由他安排，她笑說「把自己完全交給他，我感覺好像自己沒有穿衣服」。演唱會籌備了兩年多，蔡琴相當期待這次挑戰，相較於以往動輒上萬人觀眾的大型演唱會規模，「我沒有唱過500人這麼近的場地」，希望屆時能達到「蔡琴就是唱給你一個人聽的這個感覺」。她也預告要為雲門唱一首從來沒有在台上唱過的歌曲。
蔡琴表示，她的歌曲已經不是她自己一個人的。有位歌迷，唯一心願是希望能回大陸徐州看母親的墳，沒想到因為確診而離開，而在離開之前，他聽的是蔡琴的歌〈今宵多珍重〉。

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
