What is the Kurtz-Under Band (Ku-Band)?

Hello there! In today’s blog post, we’ll be diving into the fascinating world of satellite communication and exploring the concept of the Kurtz-Under Band, commonly referred to as the Ku-Band. If you’re curious about its applications, benefits, and technology, you’re in the right place! So, let’s get started.

Key Takeaways:

  • The Ku-Band is a specific frequency range used for satellite communications.
  • It offers high data transfer rates and is especially popular for direct-to-home (DTH) television broadcasting, internet connectivity, and military applications.

Understanding the Ku-Band

The Kurtz-Under Band, or the Ku-Band, is a specific range of radio frequencies commonly used in satellite communications. It was named after two scientists, G.A. Kurtz and R.P. Under, who made significant contributions to the field of satellite technology.

The Ku-Band operates at frequencies between 12 to 18 GHz, which falls between the C-Band and the K-Band. This frequency range is considered higher than the C-Band but lower than the K-Band, offering a unique set of advantages for various applications.

Applications and Benefits

The Ku-Band is widely utilized in several industries due to its exceptional capabilities. Here are some key applications and benefits of the Ku-Band:

  • Direct-to-Home (DTH) Television Broadcasting: One of the most common applications of the Ku-Band is for direct-to-home television broadcasting. Satellite TV providers leverage the Ku-Band to deliver high-quality digital programming directly to consumers’ homes. This frequency range allows for a significant number of channels and offers excellent reception.
  • Internet Connectivity: The Ku-Band also plays a vital role in providing satellite internet connectivity. It allows for high data transfer rates, making it an efficient solution for areas where terrestrial connections are not feasible or cost-effective. Remote locations, vessels at sea, and even military bases often rely on the Ku-Band for reliable internet access.
  • Military Applications: Due to its advantages, the Ku-Band is extensively used in military communications. From tactical communication systems to surveillance and intelligence gathering activities, the Ku-Band provides secure and reliable communication channels for defense purposes.


In summary, the Kurtz-Under Band, or the Ku-Band, is a specific frequency range utilized in satellite communications. With its high data transfer rates and widespread applications, such as direct-to-home television broadcasting, internet connectivity, and military operations, the Ku-Band plays a crucial role in the modern world of communication.

Whether you enjoy the convenience of satellite TV, benefit from satellite internet services, or appreciate the security provided by military communication systems, the impact of the Ku-Band is undeniable. Its innovative technology continues to shape the way we connect and communicate, bridging the distance between people around the globe.
