Application

Satellite television: Ku Band is widely used for Direct-to-Home (DTH) satellite broadcasting, delivering high-definition TV signals directly to consumers' homes. The OMT ensures that the received signals are of high quality and free from interference.

Satellite internet: Ku Band is also used for high-speed satellite internet services, particularly for remote or underserved areas. The OMT plays a crucial role in managing the polarized signals used for data transmission.
Telecommunications: In telecom backhaul systems, Ku Band is used for the transmission of large volumes of data between ground stations and satellites. The OMT ensures the separation and combination of signals in a way that maximizes data throughput.

Weather and Earth observation satellites: The Ku Band OMT is also used in satellite systems for remote sensing, weather monitoring, and earth observation. These systems require high data rates, which the OMT helps facilitate by efficiently managing polarized signals.

Interference Mitigation: By separating signals of different polarizations, OMTs help in mitigating interference between signals. This is especially important in crowded satellite communication scenarios.

Military and Defense Applications: In military communication and radar systems, X band OMTs are often used for their ability to provide high data rates and precise targeting capabilities.

Key Functionalities

Isolation: Ensures that signals of one polarization do not interfere with signals of the other polarization.

Combining: Allows the combination of signals with different polarizations for transmission or reception through a single feed system.

FAQ

Q: Why the Ku band is used for the DBS service?

A: Ku-Band VSAT antenna systems for transmit and receive that cover all Ku-Band frequencies from 12.75 to 14.5 GHz. This band provides wide beam coverage and higher throughput compare to lower bands. It allows smaller dish antennas for VSAT applications; hence installation is cheaper and easy.

Q: What is the difference between L band and Ku band?

A: Unlike the higher frequencies, such as those of the C and Ku bands, the L-band is often distinguished by its lower power specifications. As a result, the satellite phones functioning within the parameters of the L-band can rely on a significantly longer battery life than those of the higher bands.

Q: What are the advantages of Ku band radar?

A: Operating between 12-18 GHz, the Ku band offers a balance of coverage and capacity, making it the versatile choice. Benefits: Cost-Effectiveness: More affordable for end users, facilitating broader accessibility. Compact Equipment: Enables the use of smaller antennas, reducing physical and logistical constraints.

Q: What service can you provide ?

A: We have customized service and after-sale service.We can produce according to your requirments.We will give your refund or replacement if there is quality problem about our products.

Q: What is KU band used for?

A: Ku-band satellite antennas are smaller than C-band antennas, but they are susceptible to rain fade during heavy rainfall (their signals can be affected by rain absorption). Ku-band is commonly used for broadcast and VSAT (Very Small Aperture Terminal) systems on ships and vessels.

Q: What is the application of KU band frequency?

A: IEEE uses letters to signify a range of frequencies from 1 to 170 GHz. The Ku-band is mostly used for satellite TV and for VSAT systems on ships. Some Key Applications of the Ku-Band: Fixed Satellite Service (FSS) (11.7 to 12.7 GHz): This is the part of Ku-band spectrum is used for Fixed Satellite Services.

Q: What does the Ka-band stand for?

A: The designation "Ka-band" is from Kurz-above, which stems from the German word kurz, meaning "short". IEEE Ka band. Frequency range. 27–40 GHz. Wavelength range.

Q: What is the purpose of the Ku-band?

A: The Ku-band's characteristics, including its relatively high frequency and narrower bandwidth compared to Ka-band, make it well-suited for delivering high-quality video content and broadband data.

Q: How can you guarantee your products quality ? And the warranty time ?

A: We have QC department who is responsible for each point quality from raw material to finished products.Our warranty time is 3 years.

A: Our MOQ is 100 Pieces.

Q: What is your payment terms ?

A: 1)30%T/T in advance, 70%balance paid before delivery.

2)100% irrevocable LC at sight.

3)EXW price& cash price are also accepable.

4)Other payment terms can be negotiated between both sides.

Q: What is the difference between ka and Ku-band?

A: The Ka-band offers a high data transfer rate for satellite communications. Compared to the Ku-band, the Ka-band is more susceptible to rain fading and interference caused by snow and ice. A major reason for employing the Ka-band in applications is its cost-effectiveness compared to the Ku-band.

Q: What does Ku stand for in Ku-band?

A: K-under
The Ku-band includes the frequencies of 12-18 GHz. The symbol "Ku" stands for "K-under" or the band directly below the K band. You can learn more about Ku-band systems here.

Q: What is the limit of Ku-band?

A: Ku-band (12–18 GHz)
Used for satellite communications. In Europe, Ku-band downlink is used from 10.7 GHz to 12.75 GHz for direct broadcast satellite services, such as Astra.

Q: What is the range of a KU band antenna?

A: 10.9GHz to 17GHz
Frequency range allocated from 10.9GHz to 17GHz. Ku-band satellites are among the most numerous, operating for all forms of satellite communications, including video, voice and data services for consumers and enterprises. Most VSATs are in the Ku-band and are predominantly GEO-based systems.

Q: What is the bandwidth of the KU band?

A: Ku-band is a frequency band in satellite communication that spans from approximately 12 to 18 gigahertz (GHz) in the electromagnetic spectrum. The “Ku” in Ku-band stands for “K-under,” indicating that it is situated below the K-band frequencies.
