Thanks for the fast reply Dave, I am here racking my brain, trying to figure out what I should do with my antennas now. Should I take them out of the helmet, and tripod mount them with bigger metal reflectors ? Or should I just set them on the ground ?
I was amazed by the performance difference. I dont think it was lobes, because I tried this a LOT of times, and always went to NO SIGNAL no matter where I pointed the antenna when it was on my head.
So far I get this, more ground plane behind the patch is better
How far behind the patch should I mount the ground plane ? Steve Molmer had some very specific figures for the small 8 dbi 2.4 patch, I just dont know what to do with a 14 dbi 2.4 patch and also a 8 dbi 900 mhz patch.
Thanks
