  1. I do not want to buy, I want to do it myself,,,!!!!
  2. I found this on the internet and I would like to try to do it, what I need in the rest, much cheaper and easier to do (DIY) Please give me some indications .. !!!
  3. At the 85 mm diameter parabola, the focus is 33.5mm
  4. Of course, should be tried,,,,!!!!
  5. And why not try with a 85mm diameter parabolic reflector from a methane gas cylinder bottom,,,??
  6. But anyway ,these omnidirectional antennas have a very low directivity gain,,,!!!
  7. Have you tried that kind of thing ... ??
  8. About that, what do you think? With a parabolic reflector
  9. Yes, and covers a wider bandwidth
  10. Okay, I'm gonna try to do a simulation with this kind of antenna but the patches will be elliptical SOMETHING LIKE THAT,,,,
  11. Must be calculated ,,, I'll post it on the new topic with drones antennas
  12. What's so complicated to build it,,,?? A picture of a thousand words...!!!
  13. AND igs*file... uve.igs
  14. Is 4x2 ring panel antenna =16dBi gain
  15. I think in both cases you can successfully use such an antenna
  16. But with what antenna you reached 64 km...???
  17. I think the last one...!!!
  18. This antenna is not good for you? 54mmx54mm
  19. but this ,what's the matter?
  20. yah #PCB=1mm
  21. biquad2.igs h=14mm
  22. ,,,maybe this...
  23. ,,,see this...
