We recently launched the HA-02M03G01-NF, which is considered an upgrade version of HA-02M03G-NF with attributing to the persistent research of FT-RF CEO - Mr. Chen and RD team. This becomes one of the largest designs in the line of Double Ridged Antennas, despite the fact that the product weighs only 15kg. 

This product's specifications are listed below. With a frequency range of 200 MHz to 3 GHz, it was tested at 3 different distances: 1M, 3M, and 10M.

市議員黃敏儀及市府各部門24日召開內部會議，討論法拉盛五級大火的災後處理事宜，會議尚未決定拆除工作何時展開，不過預計是最近幾日，因在受災樓宇中發現了已被禁止使用、致癌材料石棉，有關部門在拆除工作展開後，也會著手處理石棉。

黃敏儀辦公室表示，尚未決定拆除工作何時展開，在受災的緬街40-10號美東商場中發現了石棉，拆除工作展開後將著手處理石棉，屆時，沒有石棉處理證書的人員都將禁止進入施工圍欄內。

辦公室人員還表示，如果石棉處理進展較快，緬街40-12號外將不再設置圍欄，方便租戶進入查探，但目前沒有具體的時間線，同樣取決於石棉處理的進度，市樓宇局檢查人員屆時可能會把圍欄往更靠近建築物的位置移動，為行人騰出更多空間。

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

此外，拆除工作開始後，一輛消防車會常駐近羅斯福大道的緬街，垃圾車也會經常在此停靠，屆時，著火點前的公車站，可能會暫時調整至法拉盛圖書館對面。
