  1. Past hour
  2. Today
  3. I think the base is magnetic for attaching to the hood of the car...!!!
  4. Yesterday
  5. BI CONE , central feed wide band (base is dielectric)
  6. BI CONE , central feed wide band (base is dielectric)
  7. I don't think so, anyway the base cone is electrically connected to the reflector.
  8. THIS I SEE might be YOUR main problem...(Cut again to eliminate the bridging between CONES , it should be open and the disc is plastic)
  9. Jomy do you have an stl file i'm interested on check it...?
  10. Last week
  11. ,,,for those who want to optimize this antenna... Magnita.cst
  12. An antenna with dual polarized, dual ports design, unexpected good results!!! RoundPatch.cst
  13. ,,,yes,it could be covered with a plastic... ,,,sorry for the mistake, D1=70 mm
  14. Excellent ... now if I'm going to try JJJJ ... only the measures of the patches are missing on the edge of the reflector. Could it be covered with a specific plastic or can it be anyone? A question ... The square bester D1 would be 99 or 69?
  15. D1=99 mm ,,,and because I saw that you like square patches...
  16. Sorry, but the D1 measurements were missing.
  17. Does it have two connectors...? Reactivity is high and Z should stay closer to 50 ohms... to be ideal...
  18. It's pretty simple, you just post there what's here.
  19. Hi, don't find a way to do this, please tell me and I'll move it
  20. Earlier
  21. ,,,,papagayor....I think your post should be here... Can you move it there...???
  22. May the double port cause the lower dbi gain or the whole parts placement, also I did not add a component in this, it's a testing project and someone that knows more than me could modify it
  23. You need something like this....
  24. Here is the biquad, with what I'm connecting to you right now. The design is based of the model from martybugs.net website. The refletor dimension is about 154mm*143mm, I did it according to what I have. Everything is still experimental, luckily working but unfortunately with a fairly poor result.
  25. Yes.. it looks good, I could try... give me more construction details
  26. Trevor approach seems the Right on the money! BUT it's using an OFFSET DISH...No SHADOW from feed and different focus F/D ratio spillage etc,
