Ka vs. Ku communication satellites

[senmeis]

Hi,

I’ve heard Ku communication satellites have a broader coverage while Ka satellites only support spot beams. Is it correct?

Can you link to where you heard/read this? And is this article helpful?

Statement from your link:

Spot beams are ‘hotter’ than conventional wide beams which must spread their energy across a wider area, and therefore have a greater ability to cut through weather. HTS systems are also designed to dynamically adjust their characteristics, such as individual beam power, to account for atmospheric conditions in a particular sub-region.

That is what I mean, but the word „ONLY“ may be exaggerated.

That's true, but the sentence just before that one implies that it applies to both KA snd KU.

In addition to this, new High Throughput Satellite (HTS) systems also better enable Ka- and Ku- alike to overcome weather issues, as compared to traditional wide beam systems.
