Help, Wifi Antenna

Looking to combine Helical antenna and Wifi adapter card in one unit.
I know there are many pitfalls at
2.4Ghz, so I'm looking for feedback on how to do this properly.

This is to extend the range of my laptop computer.

Why not to use an older 802.11g
Usb Wlan stick (good one w/ onboard chip smd ceramic antenna, much
better than w/ Pcb printed one) & some "metal" DIY "range enhancers"
? :-)

See pics & data & measures in cm
to get some clues & ideas
(text is in my native-slovene, so you won´t understand it;
sorry, still had no time to make an english version of that articles
for those UsbKey active antennas; inside URLs can be also seen at
wish...)

Have fun! :-)


There is also to check other stuff at wish:

Default Wlan Pci Card antenna_on_cable Enhancer 6dBi

Cornet enhancers for some different type antennas up to 12dBi

& also parabolic pot or wok cover (+ bucket shape add-on) "passive"
antenna experiment with at least 20dBi gain:
ST™-maxX antena (= project-X) 21dbi

well, I think that now you´ve got enough material (pics &
drawings/sketches) to check & maybe try some stuff by yourself :-))
