    MCS rates

    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 shoul
  2. 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..
  3. 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.
  4. Hello Ewa, thanks for reaching out, what kind of unconventional usage you have in mind?
  5. Hello Theodoros, unfortunately the shirt promo is long gone, the stickers still popup here and there on old stock. Happy New year to you as well!
  6. Hello, yes, UH-CC-5-24 can be used with airFiber 5XHD provided the right cables are used. There is no reason these two should not work together. What exactly do you mean by not being able to align?
  7. Hello there, (1) Our Beam efficiency values are an average over the whole working bandwidth of an antenna (at 10 equidistant frequency points), so it is much more robust and reliable than what the other supplier gave you. (2) So far no plan for a deep dish, nor shroud.
  8. Right, the fact that you get the same -60 dBm regardless of the antenna strongly points towards an issue with the radio or its software. Definitely contact MikroTik support.
  9. Thank you for the feedback, we do update the calc within a particular cycle, so we'll look into it for the next iteration.
  10. Thank you, we have bunch of new products in the pipeline, but who knows what future brings..
  11. Hi Jesse, thank you for the idea, we are constantly looking for ways to improve and bring useful products to our customers. We will look into it!
  12. I understand your situation - it is very strange to see a behavior like that and I am sorry you have to deal with this. From the antenna physics standpoint - there is no way the issue you're experiencing is caused by the antennas. A simple test would be replacing the antenna in question with anything you have - non RF elements antenna - and see if you're getting the similar result. If so, then you can be sure it is the radio. The 5 MHz channel seeing -60 dBm noise while the neighboring channels see -95 dBm noise floor strongly point at the radio. Please do try the simple test and let us k
  13. Hello, horns, as any other antennas are passive devices - they do not produce any signal, or noise. Any and every signal merely passes through them. This must be something with the radio, have you checked MikroTik user forum for similar issues?
  14. In the zip file you will find simplified 3D *.STEP and *.X_T files of the following RF elements antennas: All Symmetrical horns, all Asymmetrical horns, Twistport adaptors: TPA-PAF, TPA-ePMP, TPA-RBC These models are meant for our customers who plan networks and need the 3D antenna models for visualizations or to make sure they fit into a particular setup.
  15. Understanding the Fresnel zones effect on radio wave propagation can help you rule out problems with multipath propagation.
