Default RE: the prefect platform for aerial photography

Here is another question for Steve Molmer. I was looking at your Patch Antenna from before and the ground plane you added. I see that you said the size should be 2 waveleingths from the center left / right and up / down. 1 waveleingth for 2450 MHZ is 4.8 inches, which would make the ground plane for your 8 dBI patch 19.2 inches square. But looking at your pictues, your ground plane is somewhere around 12 inches square [sm=confused.gif] What am i doing wrong here ?

Also, what dimensions of ground plate would I need to put behind a 14 dBI patch at 2450 MHZ whose size is 8.5 X 8.5 inches ? It just about double the size of your 8 dBI patch.
