Please see subject line-- Help, Wifi Antenna-- on
alt.binaires.schematics.electronic
for a picture of my concept.
Looking to combine Helical antenna and Wifi adapter card in one unit.
My experience is limited to MW bcb. I know there are many pitfalls at
2.4Ghz, so I'm looking for feedback on how to do this properly.
I'm using the following page as my guide.

This is to extend the range of my laptop computer.

Hi Mike

You sure find some great information on the Web.

I consider this article Jason Hecker publishes
http://www.wlan.org.uk/jhecker.html to be ALL the instructions anyone
would need for constructing a 20 dB directivity WiFi antenna. I am
looking for some feedback from you on its performance.

If you plan to investigate basic effects of changing size and shape of
Helix antennas, EZNEC sure makes Helix antenna investigation easy.

I am just curious, what kind of coax and connectors are you using, and,
?how much coax?.

Jerry
Hi Jerry, Please review the picture I posted on
alt.binaires.schematics.electronic
in it you will see I'm trying to avoid connectors and cable carrying
2.4Ghz R.F.
Thanks for being the only poster to have anything near a response to my
post.

Hi Mike

My computer skills are really lacking. I dont know how to view your
images. I do spend alot of time learning about antennas. One of my
buddies tells me that he had poor results with the helix he built from the
instructions you cited. This site seems to have been better for my buddy.

Is it practical for you to use a Bridge at the input terminals of your
gain antenna so that the coax loss is minimized? That way, the antenna
(+Bridge) is connected to the computer with CAT 5 cable.
If it isnt too complicated, tell me how to view your images.

Thanks
Jerry
