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.

▲她見好市多破損折100多直呼：「賺超多！」，網友提1點勸別買。（圖／臉書社團《Costco好市多商品經驗老實說》）

不少民眾喜歡購買即期品或福利品，因該類商品只有少許瑕疵，卻能以更加實惠的價格帶回家。就有位民眾逛好市多時發現，架上有賣「包裝破損」的奶粉，該品直接折價一百多元，她直呼太划算，可該文分享上網路後引得網友擔憂，認為「凹罐」的奶粉易產生變質，勸她不要因小失大，為省錢而賠上健康。

原PO於臉書社團《Costco好市多商品經驗老實說》發文，表示自己驚奇地發現好市多也有「包裝破損」的折價方式，此牌奶粉原價一罐569元，而這兩罐有凹痕的一罐只要價450元，直接省下119元，原PO直呼「還滿划算的，如果是自己食用，內容物沒有影響，我覺得可以接受耶」。

文章發出後引得眾人關注，「至少不要報廢，也算是永續經營的一種方式」、「根本賺到，外表而已，又不影響內容物」、「避免浪費也好，各有所需」、「想買耶，沒卡」、「我一直等不到麵包凹包」、「相當於八折呢！！買了可以回家分裝」。

但多數網友則苦勸原PO別買，說明罐頭類商品的包裝有瑕疵，很可能進一步汙染內容物，「別的用品還行，食品真的不要⋯遇過衛生紙少一包特價很多，還有玩具盒損，真的有划算」、「別為了省錢玩爛自己的健康吧」、「那可不一定，外觀變形，說不定濕氣已經跑進去」、「罐頭變形有的會生銹」、「很多罐頭都會警告你外觀變形不要買, 想想為什麼吧，別衝動」、「凹罐不要買，內容物易變質，嬰兒奶粉凹罐，開罐以後發現奶粉質地不好，顆粒變粗，有點潮濕會沾黏，不到半罐的量變成會結塊，這就是不能買凹罐的原因，外觀看起來只是變形，可裡面其實也跟著產生變化了」。

據《罐頭食品類衛生標準》第2條，對金屬罐裝食品有嚴格規定，外觀不得出現膨罐、污銹罐、彈性或急跳罐、嚴重凹罐之現象，並不得有切罐、斷封、尖銳捲緣、疑似捲封、捲緣不平、唇狀、舌狀、側封等可能引起漏罐危險之情形。

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
