Since that's not my experience (even with poor antenna position) I'm
curious which unit you were using.


Venus838LPX-T.   Seems to go into a non-locked state for a proportion of the 
time but still emits a PPS signal, which increasingly deviates from true 
UTC.  That's using a 25 mm square 28 dB active patch antenna, similar to the 
antennas on other similarly located GPS receivers.  This was indoors, on the 
top floor of a two-storey building, with just the power fed to it, watching 
the LED flash.

Maybe I was unlucky?  I wonder what experience others have?
