  1. ,,,good, not everything that flies, is eating...
  2. The Polaplexer is a microwave antenna, or antenna feed, which supports two simultaneous inputs or outputs that are independent and isolated from each other by use of orthogonal (at right angles) linear polarization. The isolation can be as much as 30 - 35 dB. Its main use is to permit full duplex operation with a single antenna, in which one port is used to transmit and the other to simultaneously receive ,,,to see this ....http://www.ham-radio.com/sbms/sd/ppxrdsgn.htm
  3. ,,,see this...
  4. "No, but I'm going to try to make such an antenna on PCB...
  5. ,,,this is what you are talking about..???
  6. ,,,do you want something like that...??? Mavic Air Long Range Antenna Helical 3 cylindrical spirals and 3 hemispherical spirals ...? /
  7. ,,,okay,about pitch angle...classical=12,5-14,5degree,minimum=4-7degree,but I think it's best=17,7degree
  8. ,,,there would be other variants...!!!
  9. good, 600x400mm??....than can you do that with CNC ... ??
  10. ,,,,good, what kind of CNC machine do you have ... ??
  11. ,,,and a MiMo-antenna...
  12. yagi

    ,,,a good solution by choosing a bowl as a reflector... ,,,okay,this is my draft,,,!!!
  13. при этой антенне сейчас на работе /// !! with this antenna is now at work /// !!
  14. «Да, конечно ... !!! "Yes, of course ... !!!
  15. I think this would be a better solution...
  16. "Okay, Garry I think it's best with circular directors...
  17. ,,,look here...
  18. Yes, it is not MiMo antenna but it can be done ,,, !!!
  19. OK, I will try to do this .... !!! "but here in the forum, there is such an antenna,,,!!!
  20. ,,, why double-coated FR4 ... ??
  21. Yes, you are right ... this is your router? I think you can put 3 coplanar antennas But why do not you try this...???
  22. Hi buddy...!!! There are 3 radios on the router (2 for 2.4 GHz and 1 for 5GHz). However the 5GHz radio only uses one antenna and is only accessible on either an 802.11a or 802.11n wireless adapter and has more limited range. The other 2 antennas are for the 2.4GHz, this is to give you better coverage area for 802.11g and 802.11n. The later models of routers was able to incorporate newer technologies to allow an antenna to use both 5GHz and 2.4GHz on one antenna without degradation of signal.
