While I'm a big fan of all who run their own Stratum 1 time servers and Rob providing a hat/shield to do so is fantastic news, but...

...be aware that the GPS signal is particularly weak and you almost certainly need to connect to an external antenna with specialized cabling to have any hope of getting a reliable signal.

I'm happy to be proved wrong, but this is not a device you can install in your office (or
home) server rack and expect to get signal. Ultimately it needs to see clear sky.

And if you're thinking of installing this in a data-centre, forgeddaboutit. They charge crazy money to run a cable to an antenna on their roof.

Don't get me wrong, I absolutely applaud the effort and I might buy one myself but just be aware of the antenna requirements which seem to have been downplayed in the original posts.
