With your GPS Antenna sitting underneath all those multipath reflectors (the
other antenna's above it),
That is far from optimal from a time-nut standpoint if you are trying to get
the best performance possible.
Should strive for no metal or reflective surfaces above the GPS antenna in
any direction.

Thanks Charles,
I'm not certain myself it it's the temp chip or the way LH handles the
information. It doesn't matter like you say, there's no use doing any
measurements with the unit unlocked.
Otherwise here is a trace while I moved the antenna. Any comments on how it
reacted in holdover?

And here is where the antenna is now, this is looking straight north, so the
sky behind me is nearly clear to the horizon and straight up isn't bad
either.
