花蓮縣車齡較高的第1至3期柴油車，欠缺車上診斷系統(OBD)、廢氣再循環系統(EGR)、選擇性還原觸媒系統(SCR)等較為先進的污染控制元件診斷系統或防制設備，因此，花蓮縣環境保護局昨(15)日推出「大型柴油車補助宣導說明會」，提請業者共同維護花蓮潔淨空氣品質。

環保署統計，截至110年底止，花蓮縣籍第1至3期柴油大型客、貨車登記總數達1,886輛，由於國內車齡較高的，不像較新期別的第4至6期車，具備車上診斷系統(OBD)、廢氣再循環系統(EGR)或選擇性還原觸媒系統(SCR)等較為先進的污染控制元件診斷系統或防制設備，因此，所排放的粒狀污染物(PM)，以及氮氧化物(NOx)等空氣污染物，不容忽視，為加強推動中央現行第1至3期大型柴油車多元補助政策，同時維護花蓮空氣品質，花蓮縣環保局特別邀請港區從業業者、柴油車客、貨運業者、汽車修理廠等40個單位，辦理「第1至3期大型柴油車補助宣導說明會」。
本次說明會邀請亞東科技大學特聘教授王明文針對「大型柴油車汰舊換新補助辦法」、「大型柴油車調修燃油控制系統與加裝空氣污染防制設備補助辦法」，以及購車低利貸款利息補貼等多項政策說明，設法讓業者或車主，能充份瞭解現行補助辦法相關注意事項及補助優惠措施，進而踴躍申請補助。
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
環保局指出，「大型柴油車汰舊換新補助」及「大型柴油車調修燃油控制系統或加裝空氣污染防制設備補助」，自110年1月1日起，由環保署統籌辦理補助案受理、審查及核撥作業，為加速並提升補助案件申請審查作業的效率，環保署已建置「第1至3期大型柴油車各項補助案件線上系統」（網址：https://dvs.epa.gov.tw/），車主只需上網申請帳號及密碼，並上傳申請文件的附件，可利用手機、平板、相機等拍照上傳，請多加利用，此外環保署也成立補助措施相關業務單一服務窗口（專線：02-85124402），提供車主對於補助、系統等相關諮詢服務。
環保局強調，大型柴油車汰舊換新補助自110年12月10日起調降補助金額，目前補助階段已來到第二階段，補助金額為1萬2,000元到60萬元，且補助時間只到111年12月10日止，鼓勵業者及早更換，減少空氣污染，並可享有較高的補助金額。但如果想幫愛車更新一下，卻又不想花大錢換車，也可以透過調修燃油控制系統或是加裝空氣污防制設備的方式來達到污染改善的效果。
柴油車污染防制工作，是環保局重點工作項目之一，除秉持「罰髒不罰舊」原則，更配合中央政策積極推動各項相關補助措施，讓車主依照需求，選擇最適合的改善措施，共同維護花蓮縣良好空氣品質，創造跨世代福祉，並朝花園城市目標邁進。
