  1. can't you install wifiinfoview or any other software in the client hardware...and look back at the 722...?
  2. not is NOT the best design for less than 15dbi.... There's hundred or thousand designs for 15dbi or more (in this iste even) EASIER to MAKE With the 722 i use ONLY METAL antennas...dielectrics SUCK the juice of the signals... PS:The BIG change in VSWR is not a real life issue...is a SOFTWARE setting , intersections, port, or other...(can't change THAT much for 0.01 or 0.02)
  3. manufacturer site
  4. i'll check and confirm All this for FR4 1mm PCB
  5. AHHH! you mean BlueTooth 2400 to 2483.5 (center at 2441.75 and 83.5mhz of bandwidth) YES it's NOT hard once you decide materials and performance...
  6. I mean 10 to 25 MILLIMETRES
  7. yup...you're close 53 degrees ...but it COULD be "tweaked" and "customized"... what you mean for BT frecuency...? Yes it has a NICE 50 ohms curve.... PS: I ussually CENTER to channel 6 (2437ghz) and up and down to ch1 and 11...YMMV When we are satisfied with the results i'll give you the drawings...(dxf , dwg , cst ,etc) or jpgs with dimensions... over the original drawing
  8. NOP...this dipole arrays (doble sided pcb) ALWAYS have the REFLECTOR FAR AWAY (between 10 and 25 centimeters) PS: I don't think it would change a lot if you peel off the sleeve from reflector to panel...
  9. Originally for wimax 3.5 ghz (it SHOULD be more than 18dbi) (circular Polarization) Trying to rebuilt it for 2.4 ghz PS: doubts about the Dielectric material...(rexolite , fiber glass...?) very similar to http://Ionica 19 db , 3.5 ghz
  10. for wifi (2,4ghz) ...? (close to 19dbi) it's hard to draw ...with precision...and originally is for 3.5ghz... performance NOT guaranteed...but if you wanna try...
  11. reflector at 20 mm...(needs some refining) FR4 1mm thickness
  12. ok... i'll give it a go this week... and see how it goes...
  13. Sensitivity (how well you LISTEN) and NOT POWER (how much you YELL) is the KEY FACTOR... VSWR (closer to 1 and always under 2.1) is of utmost importance... the TL-WN722 is one of the MOST sensible radios out there (if it has the AR9271 Ver.1.0) I have managed to get connections trough several walls and long distances (with ANY good antenna) the power output...never need more than 100mw...microwaves don't need that much power...because of the high frequencies...(it could be worse with an amp) the 722 (AR9271) should be able to work great with those Yagis... PS: use the SHORTER cable possible and SOLDER direct to antenna...if posible (connectors steal signal)
  14. ...the thing (in practice is i've pointed HIGHLY DIRECTIONAL antennas to REFLECTIONS from routers i know aren't there and still get a good connection...you lose less than 3db by wall (ussually) 2.4ghz goes trough most materials non-metal... the antennas are very similar in PERFORMANCE.... which one is easier to build and keep closer to specs...for YOU...? i think the YAGIs...are easier...
  15. wn722 and ALMOST ALL wifi are 50 ohms standard... long range ...? HOW LONG...? how powerful and sensible each "radio"...? Obstacles or Line of Sight...? 14db at 90% efficiency or more is good for some kilometres without obstacles with a SENSIBLE (-96db or more ) radio (Wn722)...but depends in the router you are connecting to...
  16. on "THESE" getting more than 15dbi means using close to 20 directors...and EVEN then gain of yagis kinda HIT a maximum...maybe 16-17 dbi (Reflector AREA increase GAIN more than adding Directors) Use the BIGGER you can...imho
  17. what are the specs of the substrate (PCB) you're gonna use...? dielectric constant and thickness...
  18. http://wifipanelantenna.blogspot.com/2008/12/panel-wifi-antenna.html 1800.cst
  19. Never over 8 to 9 dbi... (its NOT good) maybe used to feed a dish...
  20. Jomy , what material i should use for the COVER...PVC...? (for that logper)...
  21. working on IT
  22. i'll give it a go...this week...
