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.

記者林坤瑋∕宜蘭報導

一名黃姓男子於一日晚間酒駕，沿途搖晃，在礁溪路二段與番割田路口時，警發現有異，尾隨要進行攔檢，黃男為逃避攔檢加速逃逸，繼續闖紅燈、逆向行駛等達八次違規，行經宜蘭市路口，第九次闖紅燈撞擊另一輛車輛，黃男的小客車也起火燒成火球，所幸無人受困，被撞駕駛送醫，黃男酒測值零點六五，警方依公共危險罪嫌移送偵辦。

據了解，廿七歲黃男有四次酒駕前科。一日晚上十時許，礁溪警方在礁溪路二段與番割田路口，發現黃男駕駛的紅色自小客車闖紅燈，車速極快並沿途搖晃，追上鳴笛要盤查，但紅車仍一路疾駛，加速逃逸，規避盤查，期間連續交通違規多達九次，闖紅燈三次、逆向行駛三次、未依號誌指示、未打方向燈、跨越槽化線各一次。

後來紅車進入宜蘭警方轄區，礁溪警方停止鳴笛，但仍在後方跟車，伺機攔檢。

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

十時多，黃男駕駛自小客車行經環市東路時，在大福路一段路口闖紅燈轉彎，卻發生車禍，先撞到一輛福斯小客車，福斯小客車失控撞到全家便利商店的柱子，黃男駕駛自小客車一開始是引擎室冒煙，後來著火成一團火球，消防獲報後趕抵現場撲滅，並順利逮捕黃男。
