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

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?

Some experimenting to come on the next S band session.
