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.

一名綽號為「藍鯨」的女網友近日在臉書社團「爆廢公社公開版」發出自己的登山照，請求廢友們幫忙一起投票，結果意外引起網友們關注，因為藍鯨發出的照片「上衣直接失蹤」，僅用登山背包的背帶遮著兩點，讓不少人驚呼「新一代登山女神」，但也引來不少惡評，讓藍鯨在個人IG抒發心情。

藍鯨在臉書社團「爆廢公社公開版」貼出自己到奇萊東稜太魯閣大山上的照片，只見貼出的照片，她穿著橘色長褲及藍黑色登山靴，沒穿上衣僅背著登山包，利用背包的背帶遮擋著重點部位，引來上千網友朝聖表示「用身體融入大自然？」、「好漂亮！已幫妳投票囉」、「攻頂才脫沒什麼，要爬山的全程穿這樣才厲害」、「我整個人沒了，好辣！」。

不過，由於照片尺度太過前衛，也引來不少網友惡評，藍鯨則在個人IG透露「沒想到這張照片會流傳大街小巷，感謝鯨粉的支持，如果早知道，一定不會放上這張，希望大家已經看到麻痺了，反正什麼難聽的話沒有聽過？畢竟是自己的選擇，你以為我有在怕嗎？反正我最大的尺度就是這樣了」。

而不少人神出藍鯨的IG後，仔細一看發現藍鯨經常在IG上分享登山的照片，不僅和男歌手謝和弦曾經一起爬山，也曾經在登頂時高舉台灣國旗，這次她參加媒體舉辦的「女力俱樂部」創作者徵選，可透過投票活動擔任該媒體的專欄作家，因此才發出照片在公開社團請求大家幫忙，本身也經營「戶外網美冒險隊」社團，累計8萬名成員，沒想到因為這次活動貼出登山照片，掀起一波話題。（編輯：張嘉哲）

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.

Open Boundary Quad-Ridged Horn Antenna Applications:

• - Low Cross-interference 
• - Antenna Measurement
• - Electromagnetic Measurement
• - Electromagnetic Compatibility Testing (EMC test)
• - Ultra-wideband Radar Detection
• - Some antennas have a compact design that makes them ideal for use with a tripod-mounted -

- Easy to make, simple design.

The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.
