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 _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
