Contemplating Ku-Band? Three Points That Will Make You a Fan


Broadcasters across America frequently turn to Ku-band uplinks and their accompanying downlinks. Used for broadcasting and two-way Internet, Ku-band is cost-effective to install and functional. We recently took a closer took at the attributes of a C-band uplink; now let’s talk about Ku-band:


Because Ku-band is used by satellite communications systems, there is little interference from microwave links and other communication technologies. (Though there ARE random stories every once in a while regarding Ku-band antennas being affected by radar detectors in cars and sensors from automatic doors, but that’s another blog entry!)

Sometimes a Ku-band uplink is just the natural choice because of a lack of space. A C-band uplink antenna needs a lot more physical space – as much as three times more – than its Ku-band counterpart. While a typical C-band uplink is 3.8 meters, the average Ku-band uplink is a mere 2.4.

There’s nothing tiny about a C-band downlinks, either. In fact, they are just as big as a C-Band uplink! It’s difficult to make a 3.8 meter C-band dish look inconspicuous, while camouflaging a ku downlink is not as much of an issue.


Okay – if your uplink is located in a rain forest (or the deep South) you may want to go with the larger, more robust C-Band antenna, but the idea that Ku-band is constantly subject to failure during attenuation is a myth. C-band IS more reliable in areas inundated with heavy precipitation – significant attenuation of the signal is a possibility, but improvements to Ku over the years in design and equipment significantly narrowed the gap.

Even in areas that get frequent snow, Ku-Band systems perform well. The secret behind a well-functioning Ku-band uplink? Choose an integrator who installs a solid system.


A Ku-band system can operate with smaller antennas and less expensive equipment, so the cost of installing a Ku-band system is significantly less than C-band. Definitely a plus for the price-conscious network.

A word of caution: installing the Ku-band system may help the bottom line, but monthly bandwidth costs are slightly higher with Ku than C-band.

Every network is different and their requirements are different, as well. What are the hurdles your network needs to overcome? Important to know, since choosing whether to utilize Ku-band or C-band may not be as simple as listing the pros and cons. Contact a reputable telecommunications company that specializes in satellite integration; allow them to help you evaluate your needs before making a decision.

Know this: since its inception over 50 years ago, satellite communications technology has only gotten better – more efficient, cost-effective and reliable. Whether C-Band or Ku, you can trust the value of satellite delivery to meet your transmission demands.
