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
  •  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.

巴西一名男子熱愛釣魚，近日他花了1300美元（約新台幣3.8萬元）買來一架無人機，想要記錄與友人的釣魚行程，沒想到竟遭到一隻短吻鱷一口吞下肚，男子完全反應不及，新玩具就失去了。

根據《每日星報》報導，一名47歲男子索薩（Luciano Souza）平時熱愛釣魚，為了記錄與友人的釣魚行程，近日花了近1300美元（約新台幣3.8萬元）買來一架無人機，7月15日，他帶著無人機到巴西中部托坎廷斯（Tocantins）的爪哇河（Javaés River）試飛。

沒想到，無人機才飛過爪哇河數公尺，突然有一隻巨大的短吻鱷從水面冒出，隨後竟迅速躍出水面把無人機咬下，之後躲入水中，索薩當嚇傻住，完全來不及反應，他表示當下還聽見短吻鱷咬碎無人機的聲音，「牠攻擊的速度極快，我才剛發現牠的身影，就目睹了這整個襲擊過程，下一秒無人機的畫面就變成了黑色，真的讓人難以置信！這隻鱷魚當時跳躍的高度高達6.5英尺（近2公尺），但我真的完全反應不過來」。

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

事後，雖然索薩與友人成功捕捉了這隻短吻鱷，但因為無人機已被咬歲且吞入鱷魚腹中，所以也無法順利取回，因此索薩考慮再購買一架無人機，去追蹤另一隻短吻鱷。
