湖人12日在主場迎戰巫師，這是庫茲馬（Kyle Kuzma）和波普（Kentavious Caldwell-Pope）被交易到巫師後首次回到湖人主場，開賽前「詹皇」詹姆斯（LeBron James）也熱情地和兩人相擁，但開賽後詹姆斯再次開啟「全力詹」模式，全場25投18中，三分球9投中6，砍下50分，外帶7籃板6助攻1阻攻，帶領湖人守住勝利。
湖人在上半場打完仍以52：59落後，第三節詹姆斯挺身而出，單節10投中6，包括2顆三分彈，狂轟19分，率領湖人打出37：23的比分逆轉超前。第四節「詹皇」持續發威，剩下2分53秒時強行切入到禁區出手，進算加罰，隨後詹姆斯興奮地仰天大吼，接著穩穩罰進，將比分拉開到114：98的16分差距。剩1分41秒時，詹姆斯在庫茲馬面前投進三分球，砍下本場第50分，「詹皇」開心地在場邊手舞足蹈，終場湖人就以122：109獲勝，終止2連敗。
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.

湖人全場4人得分上雙位數，除了詹姆斯外，孟克（Malik Monk）12投中8，三分球7投中5，拿下21分，「威少」威斯布魯克（Russell Westbrook）表現持續低迷，全場11投中2，僅攻下5分。
巫師同樣也是4人得分上雙位數，波辛吉斯（Kristaps Porzingis）14分14籃板，庫茲馬23分7籃板3助攻，波普僅獲得4分。
