A part of my mystery is solved WiFi and WiMAX I am not a big fan of WiFi
as i have some security concern but i discover that i don't have
the best antenna for 2.4 and fiddling with it is not an option. A true 2.4
is in the mail to replace it and with 2 antennas now i will be
able to install them to have vertical and horizontal polarisation and i
will see if there is some improvement at 2.4ghz when switching
between them. Nobody answer me back regarding the S band linear "not
circular" AO-51 antenna but the fades are probably due to some
antenna blocking than anything else. On the last S band session me and
Clare VE3NPC noted that the fades does not happen at the same time
on our respective QTH there is surely not some selective circular
polarisation path?
This was probably just a typo; if so, pardon the reply...
I was mixing both...hi
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.
Enjoy the new toy,
Greg KO6TH
Some experimenting to come on the next S band session.
