Design of this one is based on this pdf file : wp_omni_wireless.pdf You may search in internet for it.

I was tested this BUT without proper material for the pcb – nothing is going on. I’ll search for some old photos.

And second one :

So I make one but still cant get it working.

In the test witch netstumbler – i get too low results – may be something is wrong, maybe material of pcb board is not the same 🙁

My TEST for dwl 12dbi thing something is wrong whit my ones :

this is room test – distance ~2m
linksys wap11 whit original antenna – AP
zydas zd1211 usb whit rpsma connector soldered and 5 cm coax soldered to antennas.
various antennas tested to be able to compare result.

Second test – tv tower ~1.5 to 1.8km

Same antennas – near same ressults
rubber duckie 2dbi , smc 11 clone , trend omni – original , interline 14 dbi clone and dwl 12dbi

I tried different position of the reflector I used another piece of pcb – no results .
Maybe the material of the pcb board does matter???

Another thing is the low result of interline 14 panel – i was tested it before and get good results.

I’ll make some more tests but i’m loosing faith in this one 🙂

Here is the link to the forum from where i take blueprints for this one http://wireless.com.pt/forum/viewtopic.php?t=14978
