桃園領航猿3月份重返主場，戰績3戰2勝，不只擊退聯盟龍頭台新夢想家，還在面對新北國王的比賽中上演了大比分逆轉秀，力退對手，10日宣布再添戰力，第三名洋將中鋒貝索維奇（Nemanja Besovic）已於昨日抵台隔離，身高221公分是領航猿全隊最高，提升領航猿禁區抗衡力，全面捍衛領航猿領空。
來自塞爾維亞的貝索維奇，今年29歲，2007年開啟職業生涯迄今，先後征戰過比利時、卡達、伊朗等各國職業聯賽，近期剛結束保加利亞聯賽賽事，平均出賽16.1分鐘，貢獻10.9分、3.9籃板、投籃命中率57.8%，是名攻守兼備，投射能力極佳，且兼具高度和靈活性的中鋒。領航猿總經理陳信安認為，透過貝索維奇的身高優勢，有助於鞏固禁區，帶動球隊攻勢，提升整體戰力。
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
目前還在防疫旅館中隔離的貝索維奇，也持續自主訓練，維持最佳備戰狀態，首次來台的他，也開心分享加盟心情，他表示：「很開心能夠來到台灣，期待能認識更多台灣的人事物，也期盼自己能順利融入團隊，盡全力貢獻所能，一起拿下更多場勝利。」
