A stupid question, but why would you bother testing an antenna? I would think
with antennas so cheap and labor expensive it would be far more efficient to
make a single site visit and simply replace the suspect antennas with new ones.

To test this kind of items, you have to play with DC-blocks and bias-tees.
Rather tedious but necessary. I know as at times I have to test
questionable GPS antennae that return after lightning strikes.

Magnus what would the possibility be of measuring an 8 way satellite
splitter? The $7 wonders with dc pass through. That looks like a very nice
network analyzer you have.

Please take care that the S14WI is "smart": if it doesn't sense a DC
current on the antenna port then it reports that to the user ports and I
think it can even power off the internal amplifier, this can account for
the observed loss instead of the gain.
I did consider this. but did not have the time and energy to follow that
up at the time. It was only when I got home that I could dig up the
datasheet and manual of the S14WI. Didn't want to fry it in the lab.
I rather do an incomplete lab quick and safe. I reports warts and all.
I'll see if I get time to re-do it tomorrow.
Regardless, I want to get things going. More people than me should be
able
to do this.
Cheers,
Magnus
