全場團隊罰球命中率僅43.5%，是新北國王首役的致命傷，加上首節15分領先優勢不到2節就花光，讓他們以86比97不敵新竹街口攻城獅，在PLG季後賽首役苦吞敗仗。

P. LEAGUE+聯盟季後賽今天開打，由聯盟龍頭新竹街口攻城獅在新竹縣體育館，迎戰本季新成軍的新北國王，兩隊都力爭隊史在季後賽的首勝，主場的攻城獅技高一籌，成功逆轉攔胡。

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

國王總教練萊恩（Ryan Marchand）表示，這場比賽他們成功將攻城獅團隊得分壓制在100分內，是球隊做得好的地方，不過因全隊23罰僅10中，命中率43.5%，「這是我們做不好的地方。」

國王本土控衛李愷諺今天攻下12分、7助攻與5籃板，不過他兩罰也失手，他解釋，之前的手腕傷勢2天前復發，賽前吃了止痛藥才上場，不過他強調，只要他們本土的進攻火力回檔，加上限制對手辛巴（Sim Bhullar）再多一點，「我相信應該還是很有機會。」

今天國王本土球員當中，僅「新台灣人」戴維斯（Quincy Davis）、李愷諺與楊敬敏3人得分達到雙位數，而例行賽場均可攻下21.2分的楊敬敏，今天被對手嚴防，11投4中僅拿到13分。

楊敬敏在例行賽場均出手近17次，今天短少了6次，進攻慾望似乎有些不足，李愷諺透露，在第4節他也有提醒「學長」出手可再果斷些，他也希望有更多本土球員能跳出來，一起分擔進攻上重擔。
