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.

台灣中華職棒中信兄弟3日晚間江坤宇成功擺短棒後收打（Bastard Bunt）變成三壘側穿越安打，也成為勝利打點。象隊4日作客新莊球場賽前受訪，首席教練陳江和大讚江坤宇，「（江坤宇）玩球真是無話可說。」

3日洲際球場比賽5局下無人出局一、二壘有人，球數1好1壞，教練團下達短打戰術，富邦悍將則是內野強制驅前守備，江坤宇見狀後收棒擊出左外野安打，成為突破僵局的適時安打，江坤宇攻擊與守備都是比賽關鍵。

陳江和4日表示，江坤宇應該是看到守備員已經移動，所以收棒做攻擊。不過陳江和也說，守備方啟動內野趨前跑位的時間點沒有錯，「那是一個賭注，就是要抓bunt，你點下去就是要抓兩個（出局）。」

陳江和進一步解說，昨晚場地狀況來說，短打點下去的球比較不會滾，對方的趨前守備戰術是考驗打者，「看你敢不敢收棒、或者沒有點。」

「就是看選手臨場反應，「（江坤宇）玩球真是無話可說。」陳江和說。

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

江坤宇受訪表示，本來是有戰術要短打，是因為看到守備員已經跑了，所以收棒做攻擊，平常練習會想過，但收打判斷的時機點，比賽最能知道，「比賽狀況很多，可能就是臨場反應。」

江坤宇也強調，不管是短打還是「馬沙」，想法都是要推進跑者。
