【羅開新聞中心Minsey Weng綜合報導】總獎金八千萬日圓的Meiji Yasuda Life Insurance Ladies Yokohama Tire Golf Tournament（橫濱輪胎女子賽），週五在高知縣的Tosa Country Club（土佐鄉村俱樂部）點燃戰火，今年重返日巡賽戰場的日本選手西木裕紀子（Yukiko Nishiki）搶得好彩頭，開局擊出低於標準桿七桿的六十五桿，一桿領先笠律子（Ritsuko Ryu）。
來自兵庫縣的西木裕紀子，2014年加入日巡賽，如今邁入三十歲，多年來始終未能展開競爭力，總計生涯參加了一百零二場比賽，累積獎金不到一千七百萬日圓，其中最佳成績為2019年以10,880,237日圓名列八十一，不過季末資格考沒打好，導致上季只打了一場比賽，大多時間都在STEPUP次級賽磨練。
受到新冠疫情影響，西木裕紀子多等了一年才有機會在資格考爭取出賽權，最後名列十八，遠優於2018年的三十七名，結果上週在Daikin Orchid Ladies Golf Tournament（大金蘭花女子賽）以六十九桿的並列第四開出，可惜接下來三天沒打好，落居並列五十。
本週來到日巡賽的高知縣之戰，西木裕紀子又有絕佳的開始，第十洞出發後連下三城，回到前九洞再進帳四桿，零柏忌完美演出，不但打出個人在日巡賽的最佳成績，也是首度攻佔領先榜。
「有點不敢相信！」贏過兩座次級賽冠軍的西木裕紀子說道：「不過這才第一天，我不會去想排名的事。
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.
Recommended Accessories
- Antenna Tripod: easy and fast-changing polarisation. 100% stable handling
- SMA Cable: High-quality special SMA cable

笠律子同樣也是未失一城，不過少抓一記博蒂，繳交六十六桿，而永井花奈（Kana Nagai）、若林舞衣子（Maiko Wakabayashi）和植竹希望（Nozomi Uetake）以一桿之差並列第四。
上週開幕戰提前打包的我國選手蔡佩穎，前十二洞悶到不行，一個博蒂也沒拿到，吞下一個柏忌，不過十二洞開張後，十四洞起連下四城，終場擊出六十八桿，排名推升至並列第六。
前來衛冕的稲見萌寧（Mone Inami）只打出平標準桿的七十二桿，另一位台灣選手盧曉晴也是同樣的成績，並列五十。
