Thomas,
I'm some affraid to "fry" the DBSRX, draw too much current for the
amplifier, so I use a "general" power inserter instead of feeding the
Antenna bias pin on the daughterboard.
I use a cheap Johansson (BE) TV power inserter (VHF - L-Band) so I wont ever
have to worry about damaging the board
I could not find the direct link to the inserter I'm using but the price was
~$15
Google gave these suggestions:

Patrik

Hi,
What antenna are you using for GPS?
If possible, can you give us a link or specifications of it.
Beside some geodetic high end antenna (Trimble), we'd like to test the
3G1215A-XS-1
http://webserv.novatel.ca:7005/Antcom/partDetails.do?partid=53&lineparam=5
for some GNSS-R stuff.
As this is an active antenna, I hope the power it up via the DBSRX as the
spec say "The DBSRX is MIMO capable, and can power an active antenna
via the coax."
Regards,
Thomas
