That makes two of us.

How do you know when it occurs?  Or do you just have to poll a lot?

OK.

Plus add a decode for UBX-CFG-ANT.  You can look in driver_ubx.c
for how the other messages are decoded.  Adding a new decode is easy.

I would just add the decoder in driver_ubx.c.  Then you'll get a nice 
message.  Or just watch the raw sentences as they come back.  no need for
a raw hook.
