【羅開新聞中心Minsey Weng綜合報導】美國LPGA的亞洲系列賽轉戰Siam Country Club（暹邏鄉村俱樂部），進行總獎金一百六十萬美元的Honda LPGA Thailand（泰國女子賽），結果Pattaya Old Course（芭達雅老球場）完全擋不住頂尖高手的猛烈炮火，日本女將畑岡奈紗（Nasa Hataoka）和德國選手Esther Henseleit（愛絲特‧韓瑟萊），加上韓裔澳洲的吳秀賢（Su-Hyun Oh），紛紛擊出低於標準桿九桿的六十三桿。

畑岡奈紗在開球台上完美出擊，十八洞個果嶺全都準確攻上，其中有一半洞數抓下博蒂，包括收尾五洞的一波四博蒂攻勢，進而追平韓瑟萊，而吳秀賢後來也繳出同樣的成績單，三人都是未失一城的零柏忌演出。

「感覺自己愈來愈熟悉這座球場了，知道哪裡該去，哪裡又不該去。」之前最佳成績只有在去年第二回合打出六十七桿的畑岡奈紗說道：「所有不該去的地方都避開了，這就是今天打得這麼好的原因。」

靠著去年積分榜名列三十七，韓瑟萊晉身種子選手，首度參加這場沒有淘汰的亞洲系列賽，卻打出生涯最低桿。這位和畑岡奈紗同為二十三歲的新生代好手，開局被安排在第二組從第十洞出發，全場發動兩波連三博蒂的攻勢，她說道：「我沒有發生任何大失誤，關鍵在鐵桿發揮得很好，前半場很多都是輕鬆博蒂，後九洞好像有兩個較長的推桿，整天下來很輕鬆。」

還在尋求LPGA首勝的吳秀賢，這一天也是從第十洞開球，比賽尾聲之際在六至八洞連續博蒂，形成三人並列領先的局面，不過中國女將林希妤（Xiyu Lin）僅以一桿之差在後。

相較於上週HSBC Women’s World Championship（女子世界錦標賽）領先榜盡是東方臉孔，泰國女子賽顯得平均多了，六位選手以六十五桿並列第五，包括丹麥的Nanna Koerstz Madsen（娜娜‧柯爾茲‧梅德森）、加拿大Brooke Henderson（布魯姬‧韓德森），以及美國雙姝Lindsey Wright（琳希‧萊特）和Jennifer Kupcho（珍妮佛‧卡普秋）。

Alison Lee（艾莉森‧李）則是韓裔美國人，而泰裔法國的Celine Boutier（席琳‧波蒂兒）也算是另類的地主選手，以一張八博蒂和一柏忌的成績單開出，落後領先群兩桿。至於去年包辦前三名的泰國軍團，今年威風不再，最佳成績為Pajaree Anannarukarn（帕嘉莉‧阿蘭娜努岡）的六十八桿，暫居並列二十三。

前來衛冕的Ariya Jutanugarn（艾莉雅‧茱塔努岡）和試圖挑戰更上層樓的Atthaya Thitikul（阿塔雅‧提蒂卡），雙雙只打出七十桿，並列四十二。

我國選手李旻抓下八記博蒂，但付出三記柏忌的代價，以六十七桿並列十七，而徐薇淩少抓兩記博蒂，兩桿之差並列三十四。

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.
