香港素有美食天堂美譽，在不能出國的現今，是否想念起香港的美味呢？在香港有一種菜色，特別引人垂涎，那就是蜑家菜，而何謂蜑家菜呢？這詞看似陌生，其實菜色大家可說是非常熟悉，蜑家菜出之蜑(讀音dan)家人(香港所稱)，指的其實就是世居船上的族群，靠出海捕魚維生，入夜時分蜑家人就會將船艇停泊在能避風的岸邊，也就是大家所熟知的「避風塘」，建立了有別於香港主流文化的水上文化！
由於蜑家人居住在水上沒有冰箱，抓到什麼海鮮都必須即刻料理，因此蜑家菜的最大特色就是「新鮮」，又因為港邊風大菜餚易寒，所以第二個特色就是「熱度」。此外，因為蜑家人長期在水上生活，又沒有冰箱的情況下，他們把剩下的漁獲整理好之後掛曬，製成鹹魚和蝦乾，除了能保存食物，還能來增加菜餚風味，可謂一舉兩得。綜合上述蜑家人之生活特點所衍生而出「蜑家菜」料理美食，是許多人到香港旅遊時，必嚐的經典美味。
圓山大飯店於3月12日起，首度推出《食好嘢來圓山 蜑家菜在金龍》蜑家菜美食，午、晚餐供應，由金龍餐廳-許耀光主廚獻上30道最新鮮美味的香港特色《蜑家菜》美饌，帶您用舌尖旅遊香港，體驗香港水上人家最鮮美的貴族料理，菜色包括：「避風塘沙母佐靚干貝粥」、「漁村蒸三寶」、「菌王醬豉椒炒龍蝦」、「蜑家起司牛油松露蝦脆米」、「砂鍋雙蒜啫龍虎斑」、「紅蟳花膠蒸肉餅」等絕妙好菜！
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.
