  5. I think the base is magnetic for attaching to the hood of the car...!!!

  7. BI CONE , central feed wide band (base is dielectric)
  8. BI CONE , central feed wide band (base is dielectric)
  9. WAVY response Wide band..
  10. I don't think so, anyway the base cone is electrically connected to the reflector.
  11. 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)

  24. ,,,for those who want to optimize this antenna... Magnita.cst
  25. RoundPatch.cst
  26. An antenna with dual polarized, dual ports design, unexpected good results!!! RoundPatch.cst
  27. ,,,yes,it could be covered with a plastic... ,,,sorry for the mistake, D1=70 mm
  28. 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?
  29. D1=99 mm ,,,and because I saw that you like square patches...
  30. Sorry, but the D1 measurements were missing.

  31. Patch Feed for Parabola

    clanon replied to Admin's topic in Modeling antennas

    Does it have two connectors...? Reactivity is high and Z should stay closer to 50 ohms... to be ideal...

    Admin replied to Admin's topic in Modeling antennas

    It's pretty simple, you just post there what's here.

    Hi, don't find a way to do this, please tell me and I'll move it

    ,,,,papagayor....I think your post should be here... Can you move it there...???

  36. Patch Feed for Parabola

    papagayor replied to Admin's topic in Modeling antennas

    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

  37. Biquad and Grid Reflector

    Admin replied to rana75's topic in Antennas for 2.4 GHz band

    You need something like this....

  38. Biquad and Grid Reflector

    rana75 replied to rana75's topic in Antennas for 2.4 GHz band

    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.
  39. Yes.. it looks good, I could try... give me more construction details

  40. Biquad and Grid Reflector

    clanon replied to rana75's topic in Antennas for 2.4 GHz band

    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,
