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.

台南市栽種芭樂面積約1500公頃，為全台第2大產區，其中山上區芭樂170公頃，年產量7萬5000公斤，目前批發價1台斤35元，行情看俏；著眼於芭樂1年四季生產，有別於鳳梨2年1收、芒果1年1收，山上區農會今年首度串聯山區6農會行銷芭樂，未來也將開拓芭樂自有品牌。

據農業局統計，台南芭樂種植面積約1500公頃，年產量約為3.4萬公噸，年產值7.8億元，栽種面積前5名分別為楠西、玉井、大內、南化、山上。

山上區農會總幹事許弘霖指出，台南從山區到平地，多個行政區都有栽種芭樂，但過去並沒有特別行銷芭樂產業，許多民眾甚至不清楚原來台南也盛產優質芭樂。

因此，山上區農會今年首度串聯山區包括南化、楠西、玉井、左鎮、大內等農會，18日將於山上國小首度舉辦芭樂產業文化活動。

許弘霖指出，山上區栽種芭樂品種以珍珠與帝王為主，栽種面積170公頃，目前有100多位農民投入栽種芭樂，且有增加趨勢，主要與芭樂1年四季可生產，農民可與其他水果調節產期，如夏天盛產鳳梨，目前芭樂產量就不多，也因產量少，目前芭樂批發價1台斤35元。

南化區農會總幹事溫進添說，大家多知道南化盛產芒果，其實南化芭樂產量僅次於芒果，高居第2名經濟作物，農會每周二、五收貨，經分級後，交由貿易商集運外銷加拿大、東南亞等國。農業局指出，台南芭樂近年外銷加拿大、香港、新加坡、美國等國，頗受好評。

許弘霖說，今年第一步是整合山區芭樂打團體戰，行銷台南山區優質芭樂，另也媒合農會等周邊通路，拓展市場，接下來也打算自創芭樂品牌，創造更多元的芭樂商機。

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.
