Thanks Mark. For the cost, this seems like a worthwhile thing to try. I don’t
think the homeowners association would be too thrilled about a pizza pan on a
pole so I’ll probably have to do without.
Besides, If I mounted a pizza pan I would also endure endless teasing from from
my wife who
Hi
The thing I’m not quite understanding here - why in the world use an antenna
that needs
a ground plane when you can get one that does not need an external ground
plane?
I have three multi band GNSS antennas on the back of the house. They all get
down to
insane error circles (like a mm)

Use a resonant ground plane with four or eight tuned radials
Hi
Wind load is not a good thing when you are putting things way up in the air on
poles. Survival will
be much more likely if you don’t have to attach a great big sail to the antenna

Just tell your neighbors that you "cut the cord" and it is a new fangled
miracle "Digital" amplified UHF TV antenna. Any outside TV antenna falls
under the FCC OTARD exceptions, and your homeowners association can't do
a thing about it. :)

Put a "Bird Feeder" on the side of the house.
Even only seeing less than 1/2 the sky, this is doing OK with just a
TruePosition L1 GPS, always 7-8 sats. I have room for two antennas on the
ground plane, only have one and am using an HP 58515A active splitter.
Hopefully the attachment comes

What can I say, that antenna was $5.45, locally picked up
I don't know if that Chinese multi-band antenna needs a ground plane/pizza pan.
My antenna mount tripod has one handy, so I am using it.My first tests
were without the pan and I didn't notice any before/after differences but did
not do any extensive testing. The CSRS-PPP position error
