I have used this for RX only sites and they work great with an external
antenna and will power an antenna if you get the inductor required to pass
the DC and an SMA connector. You need to change the jumper setting to TTL.
You can power the QLG1 from the RTCM itself.

I have used the QRP Labs QLG1 GPS modules at several locations and
especially for portable receivers. You do need to change a jumper in the
RTCM to select TTL interfacing. They are $23 each in kit form, plus the
cost of an SMA PC mount connector for an external antenna. Really easy to
assemble and they acquire/lockup quickly.

That unit does look nice, but relatively pricy. Seeing as I don't need the
hi-stab, I was hoping for a lower cost option.
