Applications:

•  2GHz to 18GHz
•  6061 Aluminum metal alloy
•  Stainless Steel N-female
•  Taiwan Design, Made in Taiwan

Features:

• High Power 300W (peak) 150W (Cont)
•  DC Short lightning protection
•  Low VSWR
•  Uniform Gain
•  Consolidated performance database

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.

▲甘羅智慧出眾，有關他的傳說多不勝數。（示意圖／翻攝自百度百科）

歷史上有許多有關神童的故事，非常耐人尋味！戰國中期秦國左丞相甘茂的孫子甘羅，就是名副其實的神童；甘羅自幼聰明過人，他十二歲的時候，出使趙國，使用計謀，幫助秦國得到十幾座城池，秦始皇還特別封賞甘羅擔任上卿（相當於丞相）之職，可見得甘羅有多麼出眾；而甘羅還流傳有許多故事，其中有一次皇帝故意刁難他的爺爺甘茂，就是靠甘羅的智慧才化險為夷，令人欽佩！

有一次爺爺甘茂下朝回家心情不好，甘羅連忙上去詢問，爺爺是不是遇到什麼煩心事了？甘茂大大嘆了一口氣，表示皇帝不知道怎麼了，突然就出了個難題，非說要吃什麼公雞下的蛋，這滿朝文武大臣誰也不敢反駁，可是這蛋該到什麼地方去找呢？大家都愁壞了！

看到爺爺如此憂心，甘羅想了想，就對爺爺說：您明天不要上朝，我去，我來幫您搞定！隔天甘羅上朝後，秦王看見眾大臣之中多了一個小孩，很自然多問了兩句，甘羅很大方的自報家門，秦王疑惑：那你爺爺怎麼不來？

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

甘羅不卑不亢的回答：我爺爺在家生孩子，所以派我來說一聲。話才剛講完，大臣們都笑了，秦王則很生氣：胡說八道，哪有男人生孩子的，你們祖孫好大的膽子，來拿寡人尋開心嗎？甘羅依舊不著急：陛下都說了公雞能生蛋，那男人生孩子不也應該在情理之中嗎？

秦王不是傻子，當然聽得出來這話的弦外之音；這一番話，將秦王說得啞口無言，自知理虧的他隨即哈哈一笑，赦免了甘羅爺孫二人。大臣們也紛紛鬆了一口氣，而這件事也就算過去了，甘羅的智慧與冷靜，真不愧是神童。
