Ku Band and Compatible Products Resource Guide

Ku band is one of the major technologies used today for high-speed satellite Internet, most commonly in the maritime and air industries. Whether it is being used for business or pleasure, users out at sea or flying high in the sky want the fastest and most reliable experience possible. With the high-speed internet access we’re used to back home, it’s difficult to give that up when leaving ground (plus it’s often a requirement of today’s industries to function properly.) The performance of ku band systems are making that a reality worldwide. 


What is Ku band?

Ku band (which stand for kurz-under) is the mid-range bandwidth portion of the electromagnetic spectrum in the frequency range of 12 – 18 GHz (to include uplink and downlink.) Though it technically has a lower frequency and bandwidth than the ka-band (kurz-above) frequency, ku band is known for its reliability when used in VSAT (very small aperture terminal) systems on ships, commercial aircraft, and by NASA in space.

Extensive improvements have been made to ku band in its connectivity and coverage area in recent years. Ku-band systems now offer overlapping, multi-satellite coverage over lands and oceans for robust, reliable coverage. According to this paper on Ka and Ku Operational Considerations, ku band’s resilient coverage is even considered a strategic feature of the military. That’s quite the stamp of approval on its quality.

Benefits of Utilizing the Ku Band Frequency

What you want to know is, will the ku band frequency work when you need it to and is it the proper choice of satellite communication for you and your team?

Let’s take a look at the advantages of choosing a satellite terminal that operates on the ku band frequency.

Features of ku-band include:

  1. Ku band satellites (vary in size from 2′ to 5′ in diameter) are generally smaller than C-band satellites, making them ideal in situations where there is a limited area for install
  2. High-power signals
  3. The power of uplinks and downlinks can be increased as needed
  4. often preferable over lower frequency microwave bands is that shorter wavelengths can separate the signals of different communication satellites with a smaller parabolic antenna
  5. It offers flexibility with freedom from terrestrial operations making it easier to find a properly functioning dish site
  6. It is generally a cheaper option than C band
  7. Less vulnerable to rain fade than ka-band

Ku band satellite devices are not always used alone. In fact, they are often used to complement C-band frequency systems commonly used on cruise ships or on oil & gas platforms for ultimate reliability.

Ku Band Products

Once you’ve determined that accessing satellite internet via ku band is the right choice for your personal or business communication needs, you need to choose the right device to enable that connection. Here we will be highlighting Kymeta options for ku band as well as referencing other top of the line choices to get the device that best suits your requirements.


Kymeta is a U.S. based satellite communications company that enables reliable connectivity on mobile platforms. They offer the Kymeta U7 in three different variations to meet the ku band needs of any user. Kymeta is addressing the need for lightweight and high-throughput communication whether that’s needed on the move, in the middle of the ocean, in a remote mining site, and more.

Kyway U7 8W BUC Terminal with Modem

The Kyway U7 8W BUC terminal offers revolutionary mobile connectivity by offering a high-throughput ku band system in a lightweight and low-profile design. This “Satcom on the Move” terminal is the complete package with Block Up Converter (BUC) and iDirect modem. Whatever vehicle or vessel you need to connect, this product will meet the demands required for a reliable and fast connection.

Additional features of the Kyway U7 include:

  1. Easy install – no satellite technician required
  2. Flat-panel design is perfect for low profile installation
  3. Lower power consumption than other flat panel terminals
  4. Speeds up to 4Mbps down and 1 Mbps up
  5. Easily operable with simple power-on startup
  6. Fast tracking capability, even when on the go
  7. Great for moving vessels and vehicles
  8. Reliable even on rough seas or terrain

Kyway U7 16W BUC Terminal with Modem

You can continue to brave the elements and rely on the seamless connectivity as the U7 8W when you upgrade to the Kyway U7 16W BUC Terminal with Modem. Areas with significant rain fade may require a higher wattage of BUC power, making this a solid choice for ultimate reliability.

Kyway Go

The Kyway Go offers the ultimate solution for ku-band satellite communications on the move. This solution allows a user requiring portability to choose between the Kyway U7 8W BUC Terminal or Kyway U7 16W BUC terminal and integrate it into a transportable and ruggedized case. 

For some, fixed installation on a vessel, vehicle or a site is not ideal. Instead, you may require a portable ku band system that you can take anywhere to get satellite internet whenever and wherever you need it. That’s exactly what the Kyway Go can do.

Additional features of the Kyway Go include:

  1. Get all the incredible features of the Kyway U7 but in two weather-resistant, rugged and transportable cases
  2. One case houses the Kymeta mTenna antenna subsystem module while the other holds the interface unit which includes the modem 
  3. Ready for any environment
  4. Ideal for transport on commercial aircraft or shipping vehicles
  5. One-button operation 
  6. Mounting points for securing the Kyway Go to a number of platforms
