  1. ,,,here on this forum , is such a thing ,,,, search and you will find .... !!!
  2. ,,, I think a new post should be opened with this topic (offset dish antenna)...!!! ,,, I will open a new post and you will complete it ,,, the above mentioned will be deleted...!!!
  3. Offset satellite antenna is a section of a paraboloidal reflector with oval form. The antenna surface is not round anymore, but oval (ellipse) and symmetric. The focal point is not mounted in the middle of the dish, but to the side of the dish (offset). Thus, the advantage of this technology, is that the antenna surface is not being shadowed by the feed anymore (from the satellite's point of view). Another advantage is the less likelihood that snow will build up on the dish. The offset satellite antenna does not "look" straight up to the satellite as a Prime Focus antenna does, but it's inclined about 25° downward (almost upright position). Nevertheless, an offset dish appears for the satellite to be circular having the horizontal diameter.
  4. I considered that it is still necessary to ensure a uniform impedance over a fairly large frequency range, which is why I came to this configuration of the antenna....!!
  5. ,,, if you don't have obstacles in the direction of Base Station, it might work(but I don't think so)..!!!
  6. ,,, for a distance of 10 km, you need a parabolic offset dish...
  7. ,,,hi buddy...!!! ,,, yes it is possible, but tell me , Bester antenna with how many elements .. ???
  8. ,,, yes, it seems you are right...
  9. I don't know, let's see ... !!!
  10. ,,, no, but I can do something about ... !!! ,,, it must be known that this antenna is a fake...!!!
  11. ,,,why do not you try metal disk loaded helical antenna...???
  12. ,,, Clanon, display the dimensions please .. !!!!
  13. ,,, this antenna does not work well and is not the original...!!!
  14. Operating in the 2,4GHz band, the antenna panel integrates a state-of-the-art, dual-polarized smart antenna that offers blazingly fast and highly reliability connectivity across long distances The reflector is provided with CPC (Compound Parabolic Curve) walls.
  15. ,,,okay,I will try....!!! ,,, but it would be better to try this...
  16. ,,, try and you will see ... !!!
  17. ,,, if dielectric foam(polystyrene) is applied between the patches, the dimensions of the antenna can be reduced...
  18. OOPS,,, this antenna does not work...
  19. Clanon, this antenna is very difficult to build ... !! ,,,try to post something simpler...DIY...!!! ,,,like this...https://emagtech.com/wiki/index.php/Application_Note_3:_Designing_A_Slot-Coupled_Patch_Antenna_Array_With_A_Corporate_Feed_Network_Using_EM.Picasso
  20. ,,, can you give some dimensions ... ?? ,,, and what the vibrator looks like inside...???
  21. ,,, dimensions, please ... !!! ,,, or, I may need to install the NEC program again...!!!
  22. ,,, watching this video, I considered it necessary to try to design a Bester antenna made of FR4 fiberglass.... ,,, so I present below the simulation designed and sketches for making the antenna....
