I bought a couple of pizza pans for the GPS Patch Antenna Improvement 
Program...  preliminary results:

My  15+ year old Magellan patch antenna (actually made by Murata) would barely 
function with the Tbolt.   It was (barely) tracking three satellites and going 
through long periods of holdover.  I then mounted it on the bottom of a 16" 
pizza pan.  It is now tracking 8 satellites with no signal dropouts.
  If you are using a consumer/automotive type patch antenna,  you might want to 
try a pizza pan ground plane under it.   I am doing a 48 hour survey run to see 
how it performs compared to my other antennas.  I cannot compare it to itself 
without the pan since it would never complete the survey.

My geodetic grade antenna is a patch type antenna mounted on a 14.5" aluminum disk.  
14" diameter is a standard pizza pan size.  I am going to try mounting the TAPR 
Motorola patch to it and see what happens.  I have a good 48 survey with that antenna to 
compare to.

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?

Just for comparision. I'm curious.

Cheers,
Magnus
