Wrong.

A lot of antenna "pucks" are not just GPS antennas, but GPS receivers.
What comes out of the cable is data, not RF. That's not true of every
GPS "puck", of course, but I think it's true of the PF units.

Wrong. It's an antenna, NOT a receiver.

Even if it's the active antenna type you mention, because the output is
amplified and a lower frequency than the raw GPS signals

Wrong.

Please don't speculate where people may take it seriously,
even on R.A.S...

Thanks,

Well, humph! It wasn't speculation, it was ignorance!

So, are most of the GPS pucks are passive antennas, or are they
amplified but with no frequency conversion? And is it useful to shorten
the cable to increase signal strength?
