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.

The BG7TBL units are the best bang for your buck and support external 3.3v powered antennas.

Looking for advice on selecting GPS units for an RTCM voting project. I need units that support external active antennas.

Thanks,
