Yes, I also assumed that having the lip of the pan facing up would not be good. I mounted the antenna on the bottom of the pan. In the center of the top of the pan (the side where the pizza would be) I glued a 5/8-11 nut. This is the standard size used on most surveying instruments, antennas, and tripods. I can't flip the thing over to test the difference the lip would make (but the pan was only $3 at Target).
For my next antenna test, I also bought a cake pan. I want to see what happens when you mount the patch inside the pan. I want to try it both bare metal, and with the inside of the pan laminated in carbon fiber. The idea is the side of the pan will act as a poor man's choke ring and block signals from lower elevations. The carbon fiber lining should help absorb reflections from the insides of the pan.

I have been thinking that maybe keeping the edge/ridge upwards may be a
bad thing, so maybe flipp it over and see what ridge downards is better?
