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.

邊境開放有譜！網路PTT流出一張邊境開放的時程表，表中寫道國內預計10月10日開放入境0+7免居檢，且社區免除居家隔離措施，對此，指揮中心指揮官王必勝指出，疫情可能在下週、下下週將會是最高點，等高點過後趨勢往下時已經10月初，網路流傳的表格，內容經討論後都已經有變化，實施時間點也需要修正。

針對網路PTT流傳的邊境開放時間表，王必勝指出，因應世界在開放，可控情況下也都在規劃、討論相關開放的作為，過程中有各種提案，都還在討論中，這牽涉到各部會業務，很多細節部會還要帶回去規劃再討論，實施時間的話還要看疫情變化。

王必勝表示，今日是連續第四天4萬，模型推估上，可能下週三、下下週三會是最高點，最高點過後趨勢要往下應該已經到10月初，即使到時宣布也是要給各單位準備，應該不會在十月上旬這麼快。

而表格中提到10月10日就要開邊境，入境免檢疫，對此，王必勝強調，那內容經過討論後都已經變化，實施時間點討論後都要經過修正，討論中找出適合政策再來實施，0＋7要考慮很多面向，包含如何做總量管制、自主防疫規定、防疫車隊、旅館、禁團令、交通等多面向問題，都和各部會有很多關聯，要審慎思考、安排妥當。

因應新冠肺炎疫情，疾管署持續疫情監測與邊境管制措施，如有疑似症狀，請撥打：1922專線，或0800-001922。

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.
