7縣市防雨彈 一圖看「雨帶到北部」

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.

今（14）日受鋒面通過及東北季風增強影響，除東半部有局部短暫雨外，北部從凌晨開始出現了明顯的雨勢。氣象局長鄭明典一早在臉書貼出一張即時雷達回波圖表示，「鋒面雨帶到北台灣～」提醒民眾外出攜帶雨具。

氣象局稍早7點50分也針對7縣市發布大雨特報，鋒面通過，易有短延時強降雨，今日北部地區有局部大雨發生的機率，請注意雷擊及強陣風。

大雨特報縣市：基隆市、臺北市、新北市、桃園市、新竹市、新竹縣、苗栗縣

氣象局表示，今日大臺北地區並有局部雷雨發生，上午除北部及東半部仍有局部降雨外，中南部也會有局部短暫陣雨，中午過後隨著鋒面離開，整體降雨減少，剩下東半部及北部仍有局部短暫雨，中南部轉為多雲到晴的天氣。

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

溫度方面，北臺灣天氣轉涼，高溫約24、25度，晚上之後則會降到19、20度，其他地方較不受影響，高溫仍有28至32度，晚上低溫約20至22度。

氣象局指出，下午起嘉義以北、東半部、恆春半島沿海空曠地區及澎湖、金門、馬祖將有8至9級強陣風，沿海地區有較大風浪；馬祖、東半部及恆春半島沿海有長浪發生的機率，海邊活動請注意安全。

至於今年第1號颱風「馬勒卡」，今日凌晨2時位於鵝鑾鼻東方1760公里的海面上，持續往日本東南方海面前進。
