    WOW long time i don't visit this forum Dude above with double biquad made mistake 30 17 mm
  2. If the relector is connected to GND of cable then is better if is of aluminum
  3. yes it is very hard and wouldnt wastimg my time with such design
  4. I think that too, you must find any old satelite antenna dish for such a large distances
  5. I dont know what kind of biquad is this ,,but biquad ia biquad
  6. i think offset
  7. oK i will try add batwing to satelite dish dia 80cm
  8. Isolation between ports,i don't get it , do you mean isolation between director and central metal rod/screw ? I recently build one and work well, just is a sensitive to polarization. Jomy ..i have old satelite dish and i have in plan to use it to try pick up wifi signal ... air line cca 3- to 4 km i am not sure.. so is it better use simple biquad with reflector and add it to satelite dish (60cm...or 70 i am not sure too) or ad patch similar to this 'gun' antenna i mean just two reflector 90mm and patch 68mm... thanks !!
  9. I suspect Jomy that this must be a fake... better than double biquad....ha ha
  10. what kind of trick is that?
  11. yeah that one is really good and expensive,,,,BUT why not use ordinary satelite antenna dish and add wifi element
  12. Hi jomy somewhere is stated that this type of antenna is circular porized, that is not true at all, i recently have some problems with this antenna my son use it on another computer complain to me that he have bad signal, he mean low signal from AP.. after looking i think that something else is wrong ,AP send H polarized wifi signal and when we desolder and solder again coaxial cable inner wire into V position msignal becomes large and very very good , strenght more than 86%...So people be carefull how you polarize youer antennas!
  13. I use it as dipole on reflextor 12x12cm and work ,of course there are better antennas but work.
  14. Yes i made it and connect it yesterday to try ,,,ok it work in horizontal polarization
  15. Thanks i will try to make it!
