[time-nuts] GPS antenna selection

[Mark Sims]

You might want to try a modern GPS receiver.   I have some cheap (< $10-20) GPS modules with on board patch antennas that work indoors,  sitting on the floor of the bottom level of a two story stucco-over-wire mesh house,  away from windows,  surrounded on all sides by tall trees,  with the patch antenna face down on the floor.  They acquire and track sats quite well.
