Where are your ports? One at the source and one
at the load?

Cecil--
The s-parameter threads caused me to resurrect some test data that was taken
(by an RF engineer) before I retired. I never looked at the data other than
to see if the antenna system components met specification.

So, I have s parameters for each component taken with the latest/greatest
HP/Agilent VNA at the time. For coax cables, the VNA was connected to each
end of the coaxial cable for the measurements. Antenna data was taken with
one port of the VNA connected to the antenna input, which was a SMA
connector. The antenna was a s-band cavity antenna with a 1/4 wave probe.
The components were all 50 ohm nominal. Hopefully, this answers your
questions.

I'm curious about how to use the s-parameters for components to calculate
the "system" s-parameters. The original question is about a single antenna
fed by a transmission line, but I will probably try to analyze more
complicated hookups later.

Thanks
