Hi Luc,
Conclusion don't jump too fast on some hamfest deal as what's good for WiFI
is not always so good at 2.4ghz!
This was probably just a typo; if so, pardon the reply...
Wi-Fi and Wi-Max are different things. An antenna designed for Wi-Max
may not operate very well, as you

I have toyed with using a comercial medium gain patch array for 2.4
GHz Leos. I would guess that there is no incentive to use circular
pol for terrestrial data links. Even reflections and multi-path
signals would remain linear. Space com is a totally different deal
and circular makes sense if

an angle, or if it was some other effect.
And, yes, I could clearly receive the network traffic.

and NOT a circular polarization. Try a circularly polarized feed.
Or try a H AND a V linearly polarized antenna system,

Greg,
You got me thinking about going circular! I am wondering how you build
