HORN ANTENNA CALIBRATION

1.) The dual-polarization (HQ-Series or HR-Series) antenna has an electronic switch that may simultaneously test horizontal and vertical or +-45deg polarization, as well as a couple that can test circular polarization.
2.) The dual-polarized antenna (HQ-Series or HR-Series) is mounted on the chamber's bracket or wall (this is the way to test the antenna)
3.) If the dual-polarized antenna is being used for something else and calibration is needed, we can certainly assist.
4.)Single-polarized antennas (HA-Series, HB-Series, and other antennas) are commonly used to replace the antenna method's calibration antenna. When HA calibration is utilized, the calibration site is lost (patch loss uses a network analyzer) Enter the antenna's gain (minus the gain of the antenna, equal to the address of the object under test, return to zero)

5.) There is only one technique to compute antenna gain. The path loss patch loss subtracts the antenna's gain and substitutes the antenna under test to obtain the antenna's gain.
6.) Rotate the object under test after calculating the antenna route loss and gain calibration numbers (requires a rotating table, 2D test)
7.) If you want to read the horizontal and vertical antenna patterns at the same time with a dual-polarized antenna, an RF electronic switch, and a 3D rotating table, you can get the antenna pattern of the antenna (3D testing requires the use of HA-Series calibration twice, Horizontal and vertical or +-45deg),

8.) Antennas can be tested in a variety of methods (if you have any questions, you can provide simple photos or hand-drawn pictures, and we can assist you in the test plan)

9.) To ensure that the test value of the antenna is in compliance with international standards, all Horn products developed by FT-RF have passed internal calibration and testing in collaboration with external national research institutions, as well as third-party confirmation tests.

10.)In most ISO systems, we will demand external calibration of our test items every three years and internal self-calibration every other year. You can use the network with a set of HA-Series antennas. Calculate the path's loss using an analyzer (but usually at least three antennas can be used for internal correction, we can do internal correction by replacing the three antennas in turn)

11.)The antenna can be shipped back to Taiwan for calibration once every three years (you must know the shipping cost and the economic impact), or you can purchase a fresh set of calibrated antennas (we will calibrate the antenna internally).

11.)The antenna can be sent back to Taiwan for calibration once every three years (you must know the cost of shipping and the economic impact), or you can purchase a new set of calibrated antennas (we will calibrate the antenna internally or It is externally corrected and then sent to the customer)

12.) Antenna calibration is mostly done by an external calibration unit that must bear the ISO17025 and TAF logos.

13.)For the difference comparison test, you can use internally calibrated antennas, self-calibration, and ISO17025 antennas; this approach is frequently used in the ISO9001 series.

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.

台北居大不易！但年輕人買房更不容易！新婚夫妻買房後，對於家具、裝潢到喜歡的廚具挑選都不會一樣。有網友在PTT的WomenTalk板上發文，提到現在最常聽到的爐具，莫過於IH爐跟瓦斯爐，其優缺點各有擁護者，不禁發起閒聊，「愛做菜的妳會選IH爐還是瓦斯爐？」

此文一出就有網友秒推瓦斯爐，因為「愛做菜一定瓦斯爐」；但也有網友喜歡IH爐，提到「以前愛明火，用完IH爐，回不去了。也是每天煮，太好清潔了。」不過更有網友大推「北港香爐」，讓原發文者大笑「你用北港香爐做菜？」

該發文者內容表示，「請問愛做菜的妳，喜歡用的是IH爐還是瓦斯爐？」並說兩者各有優缺點，常聽到的就是「IH爐很好清潔，但很會挑鍋又耗電；瓦斯爐炒菜味道更好，但清潔麻煩。」他忍不住發問，「妳們呢？若有自己的房子，會選哪一個爐來做菜？」聊聊吧。

此話題引出兩派回應，有網友在下方回應瓦斯爐的好，「現在新型瓦斯爐也很好清理啊！很多新建案是樓層／開放式廚房，配合法規只能做IH」、「當然是瓦斯，沒明火怎麼叫做菜」、「目前用IH，還是比較喜歡瓦斯爐」、「瓦斯爐啊！能用瓦斯的也可以用IH，但建案只有IH的只能用IH啊！消防法規是不一樣的。」

不過也有網友喜歡IH爐，並強調電費比較省。網友說「以前愛明火，用完IH爐，回不去了。也是每天煮，太好清潔了，加上味道真的沒差」、「我家就是IH爐，光是打掃抹布擦過去搞定，這點就大勝傳統瓦斯爐」、「IH爐的轉換率比瓦斯高很多，廚房比較不會那麼熱，電費也比瓦斯費省。」

更有網友提到「已有跟瓦斯爐併爐的爐灶喔、豪山牌有出」，讓原發文者開心回應「原來還有併爐的喔？真新奇，有空去看看商品。」
