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.

彰化市長選情波瀾再起，國民黨彰化縣黨部歷經激烈民調，提名前議員黃玉芬挑戰民進黨彰化市長林世賢連任，但藍營民調落敗的彰化縣議會機要祕書張東正21日表態，正評估脫黨參選，藍營整合觸礁。

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.

彰化市長選舉這屆是經典的三足鼎立，都獲得超過3成以上選民支持，最後林世賢以4萬3085票，打敗國民黨張東正的4萬2766票和無黨黃玉芬的3萬7006票，贏得驚險。

年底民進黨提名林世賢拚連任，黃玉芬和張東正都表態捲土重來，不同的是，黃玉芬從無黨加入了國民黨，藍營舉辦電話民調，希望凝聚共識，一番激烈競爭後，黃玉芬獲得提名。

國民黨依民調提名黃玉芬，但內部雜音不斷，指出黃玉芬以無黨選代表、議員、彰化市長和立委，還曾推崇「白色的力量」，一下子投藍，讓人眼花撩亂，國民黨企圖整合兩股勢力，恐怕一加一不等於二。且近月來，都只見黃玉芬單兵作戰，一股詭異氣氛在醞釀。

藍營內部也分析，張東正黨內民調落後黃玉芬，主要是太太陳銌銌也要拚議員連任，讓黃玉芬的總支持率勝出，但政黨對比民調，張東正卻高於黃玉芬，張東正對戰林世賢更有勝算。

國民黨鬧內鬨，黃玉芬表示，如果張東正執意要參選，當初就不該參加民調初選，破壞遊戲規則。張東正則表示，如確定參選，就會脫黨、以無黨身分出戰，沒有違反黨紀的問題。

林世賢表示，張東正是優秀、認真又正直的民代，是否脫黨參選，不予置評，但從街頭看板來看，參選機率很高，希望年底是場君子之爭。林、張的支持者多樂見張東正參選，「讓年底選戰更有看頭」、「讓選民有更多選」。

上周無黨的劉坤鱧才宣布無黨參選，打破原本藍、綠對決，如今張東正也釋出再度參選的訊息，讓年底選情更詭譎。
