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.

漫步到山，天候可下，更可以瞰整台北盆地，的101也清晰可，然新店北宜路上的青潭，以及潭，也是入眼。
和美山下山之後，有一渡船，是多大台北地的民，都不一定知道的私房景，早期在碧潭吊尚未建之前，新店渡是入潭、直潭、潭、屈尺以及安坑等山的交通，但著交通建完成，民依更便利的交通方式，渡口渡的方式日凋零，如今新店渡已成新店溪，存的人力渡渡口，在交通的代，人力渡已成地方深度文化特色，搭乘同百年舟渡，在渡人的之，周遭的山青翠，此等逍自在何求。
超百年的文山，早在日期，就是台有名的茶指所，至今仍是茶育苗、繁殖、茶技的交流。
，有富的活，次老，我茶活，化身茶姑娘，戴斗笠，腰茶下，自茶的趣，偌大的茶，每年三月底始入茶的季，用自己的眼，辨一心二，手摘下茶後，再回茶集中。
另一受到大家喜的茶香糕做，也是必的目，透有茶原料，自做出郁茶香黑糖糕，品後，真的口留香，最後的泡茶座，在老的指下，一香醇美的好茶，人台茶的好滋味。
近有屈尺古道，以及小粗坑等地方特色，尤其是小粗坑，是座超百年的，1907年建，主要供基隆市、基隆港、瑞芳金瓜石牡丹坑、北市水道及北市。北市水道及北市，是台役最老的水力，外建，窗上方，以白色弧拱，屋脊，外凸窗，造仍完整保存日期貌。人以想像，可以如此美。
更多的微笑山，以及次不及完整的，文山新店情，相信值得你一探究竟，尤其家山概念，多北朋友，有了更想近的念。
