遼寧號穿宮古海峽！他：試航不是演習

HA-0218G-NF

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

•  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.

中國海軍遼寧號在1日率領7艘軍艦，從東海穿越宮古海峽進入太平洋，也讓各界猜測中國這次出海，是不是在回應上個月底美國林肯號航艦打擊群與日本自衛隊，在東海進行的兩國綜合軍事演習，備役少將于北辰在《94要客訴》節目中指出，就是擺明要告訴台灣跟日本不要忽視我的存在，但是卻被我國漁船撞見拍到，在演習的時候發生這種事就叫做笑話，「這次解放軍出海反而比較像試航」，可能就是要拍幾張照片可以PO在微博上做大內宣用，于也補充，假如軍艦上都裝滿了戰鬥裝載，他不太相信能這樣輕鬆通過宮古海峽。（請看節目44:00處：https://youtu.be/NyrcZbxcjY4）

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
