I have had good luck with cheap chinese wide-band splitters.  No problems
with L1, L2, GLONASS and more.

Like this one for $23:

Also, mostly good luck with cheap Chinese DC injectors.  Some have had
bad solder joints, easily fixed.

These have been good, for $9:

What I have not had luck with yet is finding a cheap LNA so I can recover
the gain lost in the splitters.  The ones I have tested so far have all
seriously degraded my SNRs.

Anyone know of a cheap and good L1/L2/etc. LNA?
