    • Wireless radios use MCS rates to express a few pieces of information: the QAM modulation depth, number of spatial channels, coding rate. What do these mean? Check out our IW episode for details! But, the real throughput you are likely to see in a radio online interface is most likely just approaching this maximum limit. Multipath propagation, changing weather conditions, interference, physical obstructions, and antenna alignment mismatch are other factors influencing the actual throughput. In the end, you have to understand that the throughput you see depends on many factors and it should be taken as such.
    • How the performance will be influenced depends on the material and thickness of the flat radome. If you tell us what material and thickness you want to use and the application you use it for, we can do a quick simulation for you..
    • Well, I will make a flat cover on my own, exactly as I need for my project, I do not expect RF elements to manufacture or design it for me. The only information I need is if the rounded form makes any difference for the antenna performance, which I have actually not expected. Protecting from the weather and birds would also been done by any shape. So if the shape is rounded for optimal RF performance, then how is RF influenced by it, when the cover is dielectric?
    • It is rounded for optimal RF performance, but the primary purpose of the radome is to protect the inside of the antenna from weather and birds nesting inside. The rounded radome is the only one we have and we do not plan to make flat ones.
    • I cannot go much into details, but the antenna needs a more stable cover, which will sustain some pressure, and the best when it is flat. Is there anything speaking against?
