Not that they were optimum tuned for the 2.5 GHz frequency but what polarity were the "Pringles Can" washer antennas that were so popular for Net-Stumbling a few years ago?

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 describe, on 2.4 ghz. Wi-Fi's 802.11b/g is on 2.4 ghz (channel 1 is right on top of our allocation), so a properly designed Wi-Fi antenna could be good for 13cm Ham applications.
P.S. I can use the antenna on 2.4ghz and i got fairly
good signal from AO-51 when he's in S mode but i cannot get rid out of the fades.
Could be i found why?
Pretty much every Wi-Fi antenna I've ever seen is linearly polarized. The "diversity" antennas are two separate antennas, usually one vertical and one horizontal, with separate cables going to two radios. Going circular would seem to be a no-brain improvement for the Wi-Fi crowd, but I think I've only seen one vendor do it.
Enjoy the new toy,
Greg KO6TH
